9.9.5
Version 9.9.5 Release Notes:
- Increased speed by 3x.
- Decreased memory requirements.
- (Together, these two improvements allow tSNE to be run on one million events with 12 parameters! Note that this can take two hours on a laptop.)
- Can initialize the tSNE algorithm with previously-computed LDA parameters.
- Can also initialize from previously-added PCA parameters-this means you can compute PCA on a predicate sample, copy the PCA vectors to other samples, and initialize SNEe on those identically-computed vectors for greater cross-sample similarity.
- v9.9 no longer shows uncompensated parameters in menus by default (unless you hold down option key). But when you concatenated files and add a keyword as a new parameter, it assumed this was an uncompensated parameter and didn't show it. New concatenated files add a notation that this parameter should be shown in menus.
- Spectral compensation UI: Minor updates.
- New 'Polychromatic Y by Y' creator in the Layout Editor. Access is similar to the Y by Y platform (select a single graphic and choose Y by Y from the menu or the contextual menu). Select parameters-FlowJo will create a copy of the selected plot with every pair of the selected parameters controlling color in a polychromatic plot. (This tool is useful for exploring a tSNE plot for expression and co-expression of markers-a single click to get tons of info.)
- Removed limit of 50 overlays in a single Layout graph item.
- Fix: Reducing dimensions of an LE table containing objects doesn't crash.
- Fix: Copying or pasting a textbox in the Layout Editor preserves all styling information.
- Fix (table outputs): Reduce double commas in gate names to one.
- Fix: Minor UI bugs in the custom transformation editor dialog.
- Implement smart sorting of groups, tables, and layouts in menus and lists.
- Fix: Prevent crash if PCA platform shows only one parameter.
9.6.5b Beta Release
9.6.5b Beta release notes:
- Fix crash when reading certain XML files
- Allow as many dots as desired in high-res (vector) output graphs
- Concatenation enhancements:
---If files have different compensation matrices, then export compensation parameters
---Allow proper concatenation of files with parameters in different order in file
Recent Release Updates
Changes since 9.6.2
- Exporting data files has been enhanced:
- Dialog has button to switch between compensated/uncompensated parameters
- Exporting CSV includes parameter name & stain
- When exporting all compensated (and not uncompensated) parameters, the comp matrix is included in the header
- Fixes:
- Changing compensation immediately updates items within LE groups (such as n x n plots)
- Workspace column preferences are not corrupted by copying non-global preference sets
Feb 5th 2013, Version 9.6.2 released
Changes since 9.6.1
- Tinted gates supported in PDF & SVG
- Clone gate option possible from command-click on node in WS
- Fix bug in PDF rendering of quadrant stats legend
Jan 3rd 2013, Version 9.6.1 released
Changes since 9.5.3
- PDF output. FlowJo now creates graphics as PDF format. By default, whenever a graphic is copied, the PDF format is also put on the clipboard. This makes for high-resolution graphs when pasting into PowerPoint and other programs. There are preferences that control what format is included on the clipboard; by default, both the PICT (Mac-native) and PDF will be included. You can also include SVG for programs like Intaglio. In general, most programs will select from these multiple formats the one which is best for them; however, if you find this is not the case, you can change the preferences to not include PDF or SVG. (See Preferences->Output).
- You can also choose to save a graphic as a PDF file (by preferences). When you do so, the entire graphic will appear as on a single page with no headers or footers. If you want pagination and headers and footers, then simply Print your graphic, and from the Print dialog, choose 'Save As PDF' rather than printing to your printer.
- A few rare fonts (including 'Symbol') will not appear properly in PDF outputs. If you find this to be the case, choose a different font in FlowJo.
- Minor changes:
- Workspaces can now be sorted on the basis of the Disk Filename (i.e., full path).
- Create Group dialog will identify all unique stain combinations, no matter how complex
- Minor bug fixes
Aug 27th 2012, Version 9.5.3 released
Changes since 9.5.2
- Allow FJML gate editing of histogram gate's upper bound
- No longer opens the Compensation Wizard window with portions off-screen
- When copying graphics using SVG and pasting into another application, they are always at the same relative scaling
- Exporting samples from a Group selection allows you to specify number of events to export
- Fixed disappearing layout when renaming it the same as another layout but with different upper/lower case for some letters
- Finds the appropriate hardware ethernet address under OSX.8
May 16th 2012, Version 9.5.2 released
Changes since 9.5
- When copying a compensation matrix to create a new one, the transform settings associated with that matrix are copied as well.
- General bug fixes
April 26th 2012, Version 9.5 released
Changes since 9.4.11
- Note: 'RMS'in statistics outputs has been renamed 'RMSD' (root-mean squared deviation) for clarity.
- RMSV (root mean squared variance) statistic added to cell cycle & proliferation platforms. This statistic normalizes the RMSD by the number of events, providing a value that can be compared across samples with different event numbers.
- The Compensation Wizard can now compute the 'Spillover Spreading Matrix' (SSM). The SSM provides a direct indication of which combinations of fluorochromes result in lower sensitivity from spillover spreading. Higher values in the SSM show spillovers that will reduce sensitivity more than lower values.
- Export dialog now show stain names when possible
New features:- Bug fixes:
- Fix an error that occurred rarely after dragging gates from one workspace to another.
- Fix a problem that led to very inefficient memory usage for 16 bit data files (large workspaces were hard to analyze)

- New Preference to ignore $PnG Keyword (under 'General' tab). Can be workspace-specific. Note: this preference may apply only to samples added to the workspace afterwards
Bug fixes:
- Layout item information dialog disables the foreground color selector on overlays, since that didn't do anything; disables the 'show all layers' gates' checkbox when it's not an overlay.
- Fix rare crash on reading remote (FTP) data files.
- Ancestry plots from Layout Editor are not clipped when copied and pasted into PowerPoint (before ungrouping).
- Site license access made more robust in case of server issues.

July 3rd 2008, Version 8.7.3 released
Bug fixes:
- Edit menu garbage text (undo/redo) is fixed.
- The workspace comment column text is properly added to Layout Editor Tables.
- The Group Editor dialog window doesn't show funky characters for empty parameter stain names.
- The Kinetics smoothing options are properly initialized in the kinetics window when re-opened.
- When reading DiVa 3.0 data files, the progress bar better reflects how much is left to read and compensate.
- Templates with layout editor iteration that depends on keyword iteration and discrimination now work fully.
- Templates no longer give the error that the file was not properly closed.
- Allow CellQuest data files with zero events to be added to a workspace.
- Group Edit Dialog window properly initializes the comparator menu item.
- In Layout Editor Tables that have a column for 'Gate Name' -- for sample-level nodes, the sample name is shown instead of the text 'Ungated.'
- Make sure files made from concatenated gates of compensated data have correct number of events in FCS header.
Features:
- Keyword Edit/Replace operations allow searching for blank keywords (so you can replace blank keywords with any given replacement value)
- Layout Editor overlay graphs can optionally show gates for all overlaid layers (not just the top-most). There are new UI checkboxes in the overlay information dialog to set this.
- Layout Editor Tables can show the gate name with an 'indented' option -- to make it look like the Workspace display.
- When creating a new Layout Editor Table, you can select (from the popup menu) an option to create a table that looks like the current Workspace (as much as possible); it automatically creates the appropriate columns.
- When you 'concatenate' samples or gates, you can now choose to create new parameters in the resulting data file, the contents of which are equal to keyword values from each of the samples. (Use the option-key when selecting 'concatenate' from the menu.) This let's you add identifier information (or other information) found in the keywords as a real parameter, on which you can gate, etc..
- Empty workspaces show 'Drag Samples Here' text.
- When you drag a population onto a layout graph to create an overlay (or hold down cmd-key to reassign the graphic to that population), FlowJo will now replicate that operation to ALL layout graphs that are currently selected.
- Added Concatenate User Interface link.
Changes:
- The 'Recalculate' (Immediate/When Sample Loaded/When Necessary) preference has been removed. All recalculations are now done 'lazily' -- when needed. Use the 'Recalculate' menu command (cmd-=) to force a recalculation in the workspace display.
March 4th 2008, Version 8.7.1 released
- Fixed issue with 'serial number corruption' and inability to save preferences on certain computers.

- Fixed Group Edit dialog. It now remembers all comparator states ('does not contain' etc) properly.
February 22nd 2008, Version 8.7 released
Known issues: Files with long names (>31 characters) will not be automatically re-found when moved to a new location.
Changes:
- You can now paste in an entire spreadsheet of keyword values into the Workspace for easy editing! (Click here)

- Mouse-wheel scrolling is enabled in the Group list.
- Horizontal mouse-wheel scrolling (shift-key while scrolling) is also enabled.
- FlowJo has a new Preference to annotate gates shown in graphs with generic FJML, allowing more flexibility on what to show (for example, statistics or annotations).
- Keyword lists show keywords in a more useful order (with user-defined keywords at the top); also, recently-selected keywords ('favorites') are shown first.
- Autocompensation Scripting Platform has been updated: the user-interface has been improved, and features such as compensation gate validation have been added.
- Site License information (contact information etc) is available to Site Licensees in the About FlowJo window.
- Layouts can be added and deleted immediately, without having to wait for the current one to finish drawing.
- Keyword Search & Replace: All instances of a search string within a single value are replaced at once.
- Keyword values are not subjected to 'Significant Figures' preferences when output in Tables.

Bug fixes:
- Layout Editor Batch Discriminator and Iterator keyword lists are now in the same order.
- Editing a compensation matrix a second time does not falsely flag unchanged values as changed.
- You can now delete summary statistics in the dialog window with the delete key as you would expect.
- We now correctly interpret EXPO V2 non-standard files having erroneous keyword values for parameter bit lengths.
- Batch from layout direct to printer: output is properly paginated even without going through the 'Custom...' dialog
- Kinetics no longer reports (incorrectly) that FJ-created time parameter is not monotonic.
- Platforms: when using arrow keys to move constraints, FlowJo no longer deselects the constraint.
- We now allow outputting of all ascii characters (like '�') in keyword values.
- When group gate are renamed, FlowJo prevents a '/' (slash) in the name.
- No error is generated if reading an exported data file that has compensated parameters, no uncompensated parameters, and a compensation matrix.
- Error messages are improved when there is an error reading layouts or if there are too many events on the axis.
- Robust CV calculations on biexponentially-scaled parameters are optimized.
- FlowJo allows any length boolean gate specification (It was having problems after 256 characters).
- Save As Template does not show file as being 'currently open' (a bug from 8.7b9).
- Cell cycle--remove debris gates initially are set to reasonable positions for all cases.
- Cell cycle--immediately recalculates fit if any constraint for CV is changed.
- Layout Editor--cannot select pseudocolor or polychromatic plot as graph types for overlays .

- New Preference to annotate gates shown in graphs with generic FJML, allowing more flexibility on what to show (for example, statistics or annotations)
- Keyword lists show keywords in a more useful order (with user-defined keywords at the top); also, recently-selected keywords ('favorites') are shown first
- Autocompensation Scripting Platform has been updated: the user-interface has been improved, and features such as compensation gate validation have been added
- Site License information (contact information etc) is available to Site Licensees in the 'About FlowJo' window
- Layouts can be added and deleted immediately, without having to wait for the current one to finish drawing
- Keyword Search & Replace: All instances of a search string within a single value are replaced at once
- Keyword values are not subjected to 'Significant Figures' preferences when output in Tables
Bug Fixes:
- Text boxes created for iterated layouts will have the correct sample ID
Changing Layout annotation item text contents immediately resizes the bounds to show the text - Templates with gates on the 'All Samples' group relying on compensated parameters will apply those gates when files are added
- Cluster platform no longer generates an error if launched on a gated population for a sample not yet read into memory
- Double-clicking on Kinetics analyses in the Group list does not give an error message
- Preference for Axis annotation (show parameter stain and/or name) is obeyed for Layouts and Workspaces
- Preferences for print headers and footers are obeyed for Layouts and Workspaces
- Create Groups and Show Graph for Table Editor works properly after Table has been sorted
- Keywords are sorted correctly in Keyword lists
Layout Editor Menu items are greyed out when Graph Windows are foremost
August 13th 2007, Version 8.5.3 released
- Open file dialogs are properly titled (e.g., 'Open Workspace' or 'Open Samples').
- The menu item 'Create Group From Keyword Value' has been removed; a single user interface is now used for all keyword-related group creations.
- You can now drag samples from one workspace to another by dropping them on a group in the destination workspace; the samples are added directly to that group.
- For new workspaces, the Table and Layout Editor windows are by default placed just to the right of the workspace, rather than on the right edge of the screen.
- There is a new Preference for using generic FJML commands for all gate annotations in graph windows [NOTE: This requires more documentation].
- General undo preference off by default
- If general undo is slowing down too much, will warn user to turn preference off
- Comparison Platform: The checkbox for 'show difference' is properly initialized.
- SciBook: Exporting a Layout Batch View does not crash.
- Polyvariate Graphs: You can no longer select 'Histogram' or 'CDF' from the contextual menu or main menu.
- Table Summary Statistics: You can now immediately access the most recently-created table column; changing group names is performed correctly.
- Derived Parameters: Parameters are no longer randomly renamed on occasion.
- The Preference for 'Show All Keywords in Lists' is obeyed for all keyword selection dialogs.
- The Preference for 'Default number of columns' in Batch Layout creation is used correctly.
- Opening old workspace could cause undo to crash, until file was saved
- Fixed crash when creating statistics table object in layout editor
- Fixed occasional debugging error message on certain operations that were OK (like dragging gates to lots of samples)
- Truncated (bad) FCS files now generate an error message rather than a crash
- Fixed crash when reading a kinetics file where the last event's time parameter value is out of range
- Fixed sorting of file names in workspace (when they had numeric components only)
- Fixed the scaling factor for linear DiVa data file that are accessed via FTP
- Preference Sets: You can now store the current preferences as a 'Set' (via the Preferences dialog). You can save as many different sets as you want. Later, you can open the Preferences (for the Application, Workspace, or Layout), and copy from one of the sets to engage those preferences. That way you can keep different settings for different environments. The FlowJo menu has a menu item to directly switch to a given set of Preferences (for the Application). (One application: 'Style sheets' for layouts: you could designate the default fonts, graph styles, headers & footers and such for different layouts to be specific Preference sets. Then, when you create a new layout, you can copy the Preference set for the desired view for that Layout).
- Table Summary Statistics: You can now add any number of summary statistics to Tables, including statistics computed on a subset of the rows in a table. Statistics can include Mean, Median, CV, Minimum, Maximum, Range, IQR, and even T-Tests and Wilcoxon Rank tests on different subsets of data within each column. To define or change these statistics, click on the 'Sigma' (Statistics) button in the Table Editor (each table can have different summary statistics).
- Statistics: Statistics computed on distributions (e.g., median fluorescence, mean, CV, etc) are now considered 'invalid' if there are insufficient events on which to compute the statistic. By default, the minimum number of events is 1 for most statistics (or 2, for CV and SD). In addition, the statistic 'Frequency of parent' (and similar) are considered invalid if there are no events in the parent subset.
- There is a new preference, under 'General', where you can increase the minimum number of events on which to calculate these statistics. 'Invalid' statistics are represented by a bullet ('�') in all output places. 'Invalid' values are ignored by the Table Editor when computing summary statistics or formulas (a Table formula that has an invalid statistic as one of its inputs will generate an invalid output value).
- Compensation Wizard: Performance enhancements; better identification of positive controls.
- Minor additions:
- Workspaces store a history of all versions of FlowJo that they were saved with (accessible when 'Save As XML' is chosen).
- Pseudocolor graphs obey dot size (2, 4, or 8 only) preference
- FlowJo's file reading has been optimized to take advantage of multiprocessor machines for faster data loading
- A number of bug fixes:
- Compensating DiVa data that has linear parameters now properly stores and re-reads the information when the workspace is saved.
- A situation where layouts could be saved in a corrupted fashion has been fixed; workspaces that have this issue will now be properly read.
- Accommodates new Coulter-generated files
- Layout Graphics now obey Layout-specific preferences
- Workspaces can only be opened once simultaneously
- Statistics tables in Layout Editor obey significant figures preference
- Allow data files with more than 128 parameters
- Fix reading $COMP keyword compensation matrices (e.g., Coulter data files)
- Properly initialize Preferences on new computers

- Fix: Bug could lead to crash while reading some workspaces.
- Fixed an occasional crash on the Compensation Wizard
- Fixed a bug where (on Intel Macs) the Proliferation Platform would not compute a model for some fits
- Fixed a bug where keyword values from BioTrue-generated workspaces might have an extra character at the end
- Table columns can now have custom significant figures assigned (in the formatting dialog for table columns)
- Compensation Wizard is significantly improved:
- Graphical display uses smaller graphs if there are a lot of compensation parameters
- Much better (if not perfect!) identification of unstained samples
- Refers to unstained as 'Unstained' rather than 'Universal Negative'
- You may have multiple unstained controls (for example, cells, different kinds of beads); the platform will automatically select the appropriate control based on the Forward Scatter matching
- You can choose to have the Wizard add 'Clean-up' gates, which will add tight gates around the fluorescence distribution of the positive controls
- You can choose to have the Wizard add scatter gates to identify lymphocytes or singlet bead populations
- There is a menu that controls what happens when you create the matrix: by default, the matrix will automatically be applied to all samples and the Wizard finishes
- Graphical display uses smaller graphs if there are a lot of compensation parameters
- Concatenating files does not export the compensated parameters (re-compensate after concatenating)
- You can now choose to show the full data file path on the disk, as a column in the Workspace window
- A number of bug fixes:
- Derived parameters (and Calibrated parameters) created on Intel Macs are properly saved in workspaces
- The Calibration platform manual definition will draw only one axis scaling
- Grouping in the Layout Editor preserves front-to-back layering
- Intel Macs can now update purple (version 6) dongles
- Derived parameters dialog properly enables log and linear parameter menus
- General Undo crashing repaired
- Table Editor summary statistics shown with desired number of significant figures
- Table Editor formulas that referred to specific rows of a column now work
- Boolean gates allow parentheses in the gate specification
- Showing gate coordinates for Boolean gates in the workspace shows the full specification
- Group gate synchronizing was fixed to handle a case where multiple gates, derived from different groups, were modified; the entire gating tree was incorrectly synchronized to one of the groups
January 9th 2007, Version 8.3 released
- Derived parameters (and Calibrated parameters) created on Intel Macs are properly saved in workspaces
- Fixed:Unknown corruption leading to bad keyword values causing an error building tables with those keywords.
- Saving incrementing file name versions will tag the number before the filetype ('abc.001.jo'); will only keep most recent in 'recent items' menu;
- Save as will not create extra blank file.
- Auto dialog answers will generally not store 'Cancel' answers to prevent confusion.
- Tweaked Compensation wizard auto-assignments.
- Exporting histograms includes a third column as scale fluorescence (bin / fluor / count.)
- Fixed: Edit comp matrices on intel macs wouldn't allow non-integer values.
- Long gate names are abbreviated in graph windows (abc/ad...def/fjd/).
- Fixed: Annotation items automatically resize to accommodate changing info!
- Text boxes can now be set (default) to resize automatically to text. If you resize via drag, then the flag is set off. Old textboxes do not acquire this flag.
- Fixed: reading packed data files (e.g., 9 bit files.)
- Modified: storing keychain information for servers with multiple names will store under original & modified host name.
- Preferences: changed how they are stored. Workspaces store data transform prefs with WS; not affected by global prefs.
- Linear axis values are abbreviated with 'K' (like 100K) to make them shorter
- When overlaying more than 12 items in a Layout Editor graphic, the colors continue to rotate (rather than being only red)
- Cumulative records for FlowJo analysis times (under 'About FlowJo') are properly incremented
- There is a new Platform, 'Sample Validity Testing.' This platform allows you to determine if the events collected during acquisition are uniform (i.e., unchanging over time). You can identify files which have clogs, discontinuities, or other problems. The platform can be automatically invoked for every data file through a Preference; the settings which fine tune how FlowJo identifies potential problems are set in the Platform window.
- Boolean gates that do not contain 'or' operators (for example, as created by the 'Create Combination' platform) now compute 30 times faster!
- In the Table Editor, there are now contextual menus (click and hold, or control-click, on table column definitions) which allow you to modify a row: move it to the top or bottom of the list; delete it; edit it; or change it to a different kind of definition.
- FlowJo will now rename duplicate parameter names (in Dako files); duplicate names led to a lot of different problems. For older workspaces that refer to such files, open them in this version, and just save them. Any error messages will now go away.
- Transformations defined on DiVa-generated compensation matrices will be applied to all files with 'similar' compensation matrices. DiVa generates compensation matrices that have trivial differences that caused FlowJo to think they were actually different.
- If you copy a table with formulas to the Layout Editor, FlowJo now informs you that formulas are not supported in Layout Editor Tables.
- Linear axis values are abbreviated with 'K' (like 100K) to make them shorter
- Several stability issues were addressed.
- Proliferation statistics will now appear in Tables even if the Proliferation model has not yet computed.
- If the files were loaded in the Compensation Wizard which did not have fluorescence parameters found in other files, then the Wizard could crash. Now only parameters that are common to all files are selectable for generating compensation matrices.
- Biexponential transformation parameters are correctly initialized in preferences.
- Correctly reads workspace files that were modified on an Intel Macintosh using an early 8.0 version of FlowJo, but caused a crash when reading.
- Selecting 'Save' menu when 'SciBook' is open will save SciBook entry to disk; changing a SciBook comment will mark the Workspace as having been changed so it can be Saved immediately.
- When overlaying more than 12 items in a Layout Editor graphic, the colors continue to rotate (rather than being only red)
- Cumulative records for FlowJo analysis times (under 'About FlowJo') are properly incremented
- Correctly reads workspace files modified on an intel Mac using an early 8.0 version of FlowJo that caused crashes while reading
- Does not crash when double-clicking on layout graphs that have long gating path names
- Correctly copies table outputs to layouts
- Properly saves statistics tables created in layouts
- Drop-down menus in Compensation wizard work
- Polyvariate gates are saved such that they can be read on non-Intel macintoshes
- Linear parameter scaling does not change with each workspace save for remote-access datafiles
- Fixed: Quadrant gate statistics in tables and layouts
- Fixed: Copying Graphs from Layouts with history gating are properly cropped when pasted into other applications
- Table Editor Formula entry window is now resizeable
- Derived Parameters: New 'Edit' button allows you to edit a previously-defined algebraic formula.
- Prevent crash in Multi-Sample Distancing Platform dialog if no sample files are available for comparison.
- Changed name of dialog box from 'Layout Item Definition' to 'Graph Definition', to be consistent with the Windows version.
- A 'workspace' created from the BioTrue server contains translations of the original FCS file headers. If the original FCS header file contained a keyword with a blank value, the BioTrue translation of that header would confuse FlowJo, causing it to incorrectly read the header information after that value. If multiple Samples were included, this would cause some samples to have incorrect names. This condition has been corrected. FlowJo will now read the translated header correctly.
- The FlowJo Workspace window created from a BioTrue '.jo' file, is now given the name of the file instead of being an unnamed workspace.
- Added preference to enable SFTP file transfer.
- Added dialog box to ask for SFTP User name to initiate file download from BioTrue SFTP server.
- Added dialog box to ask for user, workspace, and destination information to initiate SFTP file transfer when saving a Workspace to a remote SFTP server.
- In the About Box, changed 'Serial: ' to be 'Serial: Dongle' when authentication is via a dongle.
- Now works with V8 'purple' dongles on an Intel Mac.
- Changed the Graph Window so that the text, 'Warning! More than X% of events on the axis!', appears above the graph pane, rather than touching it.
- Fixed crashing bug when calculating the Kinetics Platform.
- Fixed crashing bug while attempting to quit with the Kinetics window still open.
- Fixed: Cell cycle statistics overlay: axis label does not overlap with axis ticks.
- AutoCompensation scripts now generate exactly correct matrices when universal negative is used. Previously, off by a small amount for low fluorescence controls.
- MultiDimCompare: Does not crash when computing multiple chi square.
- Batch creation (to preview): Only warns on too-large layout size if ... too large!
- FlowJo properly sets picture boundaries for graphics copied from layout editor to show all axes without needing to ungroup.
- Workspace files with Derived Parameters will display correctly on an Intel-based Mac.
- Renaming a gate at the group level is properly handled so that all references to the samples' gate are also updated.
- Fixed several instances where old (PowerPC) workspace files might not open properly on Intel Macs.
- Fixed dongle-upgrade URL to paste the old dongle ID into the upgrade web page.
- Added check box to select SFTP for file download and upload. Currently disabled.
- Fixed a problem on Intel-Macs where some older workspace files would not load properly, resulting in the dreaded 'You've uncovered a defect in the program' assertion-failure dialog box.
- Fixed a few more instances of handle-based I/O not being 'swapped' properly on an Intel-Mac.
- Fixed problems on Intel-Macs where older workspace files would 'lose track' of sample files in some instances. That is, if you load an older workspace and double-click on a sample, a Graph Window will display the expected graph, rather than asking the user to find the FCS file.
- Fixed problem with LE text annotation edit dialog, which caused all menu items to be disabled, and prevented the program from responding to further command events. Changed PPob resource #4319.
- Removed second, unused 'Workspace' 'Rename...' menu item, #2023.
- Removed 'Extended' attribute from menu items:
'Edit' 'Select equivalent nodes' (#2032)
'Workspace' 'Add Samples into Group...' ('AddG') - Changed 'ValidThumbDrive' to set 'gDongleAttached' so that the 'FlowJo' 'Serial Number' menu item is disabled. This now disables the 'Serial Number...' menu item when a valid thumb drive is found.
- Fixed uninitialized variable in 'MultiDimCompare::MultiChiSquare', causing a crash on an Intel Box when the first sample in a Multi-Sample Compare is not selected.
- Fixed printing problem on Intel-Macs, where the Y-axis labels were rotated by other than 90 degrees. C
- hanged FlowJo.rsrc 'Miscellaneous Strings' (resource #2100), string #240 to read:
FlowJo does not support a HASP key (purple dongle) on an Intel-based Mac. Please click on 'About Dongles' to view our trouble-shooting web page. - Added version resource '8.0.0' to the SNConverter tool, so we can tell when it has been updated.
- Fixed problem in 'FTableViewer', where the 'fNodeForCell' was not being completely initialized, nor was it being indexed incorrectly. When trying to create a new Group from a list of cells in a table, via 'FTableViewer::CreateGroup', function 'FTableViewer::GetPopulationForCell' would loop forever looking for the last cell.
- Fixed problem where an exception would occur on an Intel-Mac when reading workspaces with Calibration tables.
- Fixed problem that would prevent FlowJo from recognizing a black dongle if another USB device with a serial number was also attached.

- Statistics Window shows larger fonts and doesn't allow 'Add to all compensated parameters' if no compensated parameters exist
- Intermittent Site License validation problems have been corrected.
- Fixed problem that would prevent FlowJo from recognizing a black dongle if another USB device with a serial number was also attached.
- No more hanging when the Tree Star web site is impossible to reach
- Can create derived parameters on Cyan-acquired data
- Workspace statistics don't disappear when a recalculate is performed
- Read all Coulter data files
- Cell cycle: constraining peaks to gate positions is now correctly saved
- Cell cycle: option to use pattern fill for graphs is correctly saved
- Annotation items in layouts are properly filled for batch outputs
- 'FS LIN' and 'SS LIN' parameters are now recognized as scatter parameters
- Improved performance and stability
- Significant performance improvement noticeable when compiling large layouts or tables-particularly when hundreds or thousands of samples are involved!
- Fix text issues in dialogs on some computers running OS9.2.2.
- Summit 4.x files with incorrect data location specification keywords are now read in properly.
- The compensation definition window can now be resized to allow for long parameter names.
- Fixed: Memory was slowly being used up by doing large numbers of text boxes in the Layout Editor
- Fixed: Tables with negative numbers in the statistics will now show means & standard deviations.
- A number of optimizations and bug fixes were done to prevent crashes that occur during large computational demands; stability should be much better.
- Site licensees are validated more efficiently Preferences:
- There is a new preference to define the default sort order for samples in the workspace Workspaces:
- Workspaces are now read in and saved much more efficiently. Note: the first time you read in an older workspace, it may be much slower; as soon as you save in the new format, it will be considerably faster!
- Workspace sort criteria are now 'persistent': if you add new files (or for templates), the files will be automatically sorted according to the last selected criteria. In addition, when you define the sort criteria, you can make them the default for all new workspaces.
- Workspace sort criteria can be individually set to be increasing or decreasing values.
- Unreferenced samples are now removed from workspaces (making templates much smaller).
- XML format has been modified (more similar to PC version). This format is still being updated and is not guaranteed to be consistent with future revisions of FlowJo.
- Tables with keyword values that have
or display properly - You can copy a series of custom column heading names (from Excel or Word, separated by returns) into any column heading name – the entire series is copied to the subsequent table columns (hit return or tab after pasting). In this way, you can edit the column names in a different program and then copy them in all at once.
- The mean and std. dev. are filled in only for valid calculations (e.g., they are left blank for text columns)
- reading newest Coulter data files
- Cell cycle models that constrain to a region--constraint is saved after closing & reopening
- Cell cycle platform option to display pattern filled models is properly saved
- Annotation items for Layout Graphs are properly built in batch reports 'FS LIN' and 'SS LIN' are recognized as forward and side scatter parameters
- Fixed bug that could cause crash during gate computation while other tasks were happening-improved stabililty!
- When directing a batch output directly to the Printer, the page information is properly initialized without having to go through the 'Custom' settings button.
- Fix: Preferences correctly reads layout color palette for overlay colors
- Fix: Bug that could cause rare occasional crashes when reading files
- Fix: When choosing to sort the workspace, the current sort criteria are displayed

- Opening graph windows no longer occasionally reset the Layout iteration value
- Cycling graphs (next/previous) no longer cause a rare crash that happens when gate frequencies were shown
- Modifying a series of gates that are all group-synchronized no longer causes a rare crash
- $SPILLOVER keyword values are properly supported
- Allow dragging gates from one workspace to another if the destination sample is selected
- Crash no longer occurs if changing a graph while an outlier plot is computed
- Selecting a graph from a sample not in the current group does not make that sample temporarily appear in the workspace window

- Boolean gate specifications are no longer case-sensitive
- The Layout batch Preview will not crash if the display is too large to show on-screen
- The line color for boxes drawn around text is correct in batched layouts
- Summit data files with badly-formatted $SPILL keyword (Summit version 4.1) are now read in (an error message is shown) but no compensation parameters are added. These files can be compensated the usual way in FlowJo, using appropriate compensation controls.
- FlowJo does not crash if you try to delete the only layer listed in the Legend Item for a Layout Graphic.
- Batch layout generation: if Iterate by Nth (n > 1), the resulting layout's discriminator is properly set.
- Files with long names (>31 characters) will not be automatically re-found when moved to a new location.
- There is a new preference to control the default naming scheme for new Quadrant gates (you can choose to have only 'Q#', where the number increments for each new quadrant set; you can choose to add the stain names; and, as before, you can choose whether or not to ask for a prefix to the gate name).
- The Backgating analysis now shows a legend of gates applied for each graphic, to better illustrate what is being shown. In addition, the last graphic in the window is no longer a backgating analysis (as there as no useful information for that level), but rather shows a simple overlay of the gated population.
- There is a new gating tool to create two gates that bisect a histogram; while tracking with the mouse with this tool active, the graph window will show live statistics (like the quadrant tool).
- A new menu item, 'Show defining gate', allows you to quickly access the graph that defined any selected subset.
- Contour plots can no longer be drawn as unsmoothed.
- Log contour plots do not allow you to select 'show outliers', which was meaningless for this display.
- Kinetics analyses now show the threshold value used for calculations in the kinetics window.
- Grid lines for linear parameters are now drawn to match major axis tick marks.
- Corrects Summit Compensation matrices (for all versions of Summit).
- FlowJo now supports the FCS3.1 keyword '$SPILLOVER' as specified in the proposal.
- The compensation matrix name (if FlowJo was used to create the compensation) is now stored in a keyword ('FJ_CompMatrixName'),
- The compensation definition window has new buttons to calculate and close; to clear all positive & negative gates from the boxes; and has better selection of gates in the boxes.
- FlowJo keeps statistics of how many different kinds of operations you perform (number of files analyzed, gates created, events read): Choose 'About FlowJo', and click on the disclosure triangle near the bottom of the window.
- All 'Confirmation' dialog windows have button names that better explain what the two choices are (instead of just 'Yes' or 'No').
- When editing the attributes of platform graphics in the Layout Editor, you can now set additional options such as the colors and size of the graph.
- Scrolling large layouts is much quicker.
- You can now change fonts for individual layout items.
- For overlay legends, the cursor will change when targeting the color or line style controls to aid in identifying where to click.

- Preferences reorganized (a 'Platforms' preferences panel added)
- The preference for copying the FCS Comment keyword into the workspace annotation was removed
- A new button clears all memorized auto-answers for confirmation dialog windows
- 1. Default statistics that are added to layout editor when Cell Cycle platform is dragged in (and the 'auto-create statistic table for platforms' preference is enabled).
- 2. Default statistics that are added to layout editor when Proliferation platform is dragged in (and the 'auto-create statistic table for platforms' preference is enabled).
- 3. Default columns to be created whenever a new overlay legend is created in the layout editor.
- 4. Default colors and graph types for Backgating analysis (these can be set either through the Preferences dialog, or by selecting the checkbox before closing a Backgating window).
- 5. The default scheme by which to name new Quadrant gates (you can choose any of 'Q#', where the # increments for all new quads for a subset; the stain names (e.g., CD3+CD4-); a prefix that is asked for when the quads are created).
- Correct sorting of file names that have the format 'name.#.#' (like abc.040602.001)
- Line color of histogram was sometimes forgotten when the graphic info dialog was opened in Layout Editor
- Distribute horizontally in Layout Editor works even if items are too close together
- Selecting 'About FlowJo' no longer puts application in Demonstration mode
- Layout items now correctly show cell counts after batching
- Resizing Proliferation window properly draws the model histograms
- Copy table from Multisample compare platform fixed
- Inserting keywords for specific samples in Layout Editor Text chooses correct sample (was one off)
- Occasionally, 10.e-4 would be displayed as 10.e-3 for frequency in Workspace
- Correctly displays time parameter for BD files using the 'TimeTicks' keyword
- Copying from layouts no longer clips the right or top edge of certain graphs
- Fix Copy/Paste of a single textbox in the Layout Editor creates a new text box, not a picture of a text box
- Group-synchronized gates don't crash if more than 1 is simultaneously changed (like quadrants)

- Fixed a memory allocation bug that could cause apparently random crashes
- Reading old layouts with legend overlays will now properly initialize the legends instead of leaving them blank
- Changing the threshold value for a Kinetics analysis forces an immediate recalculation
- Thick lines in the layout editor are better handled (selection and arrows)
- Avoid page breaks in the Layout Editor will not cause a graph and its annotation or legend to be put on different pages
- Create group window: Removing a criterion clears it; complex formulas doing comparisons on string values now work
- Clicking escape while drawing a gate now cancels the gate creation
- Selection of gate constraints in Cell Cycle platform was corrected
- Histogram gate lines in layout editor (and exported graphs) don't extend beyond edge of graph
- Adding a statistic to a group based on a parameter that has a ')' in its name no longer crashes
- Putting commas in custom table column names no longer alters the formatting of table headings
- Dragging a PICT file into the Layout Editor now refreshes the view immediately
- Tables dragged into the Layout Editor now automatically refresh statistics when gates are moved
- Double-click timing to open graphs from the workspace window restored to proper functioning
- Changing a gate does not reset the Layout Editor iteration to 'off'
- Only the 17th parameter in a file could not be compensated: now it can!

- Fixed: You can now compensate the 17th parameter in a data file
- Fixed bugs that crept up in beta versions:
- Contextual menu for gates restored
- Group-based synchronizing multiple gates (like quads) fixed
- Version Locking.You can now 'lock' a version of FlowJo on a given computer (which will apply to all users on that computer). This lock ensures that no other version of FlowJo will be used for data analysis on that computer. This feature is useful for laboratories who have validated a given version of FlowJo and want to ensure that no analysis is done by a different version. To 'Lock' a given version, choose the Lock command under the file menu, enter an Administrator username and password, and then follow the instructions. Locking can be performed in a password-protected fashion (if desired). NOTE: 'Locking' a FlowJo will not prevent versions 6.0 (or 4.x) from launching, because they cannot check for this feature. However, these older versions of FlowJo cannot read workspaces saved by this (or future) versions of FlowJo, so there is no risk of analysis by the wrong version. NOTE: Because the 'lock' feature will apply to all users on that computer, you must have Administrator privileges. When you choose 'Lock', you will be asked by the Macintosh operating system to authenticate a Username with Administration privileges.
- Complex Group Definitions. Sample Groups can now be defined based on arbitrarily complex combinations of keyword information. In the Group Definition Dialog, you can convert current keyword restrictions to a formula, and continue to extend this formula to be as complex as you wish! Formulas can contain complex string manipulations, so you can search for substrings within keyword values, etc.
- Opening sets of graphs.Through the preferences, you can now define one or more 'Graph Sets'. These are predefined sets of graphs (with specific X and Y parameters defined for each). Any defined graph sets will appear in the contextual menu when you click on a sample or subset; choosing that Graph Set will cause one window for each defined parameter pair to be opened for that sample. This allows you to predefine combination of parameters to view simultaneously for each subset. (Use 'option-Next' or 'option-previous' to move all graph windows forward to the next or previous sample simultaneously).
- Copying Boolean gates will now notify you if the subsets on which they depend are not found in the destination. In addition, if you delete a subset on which a Boolean gate depends, you will also be notified that this is the case.
- FlowJo will now read badly-formatted legacy Cytomics FCS files.
- XML Workspaces: Versions 6.x give you the option to save as XML (and can read such workspaces as well). At this time, Tree Star does not guarantee that the XML format will be compatible with future versions of FlowJo; we are in the process of evolving this format to be consistent with the PC version. If you have suggestions or questions regarding the FlowJo XML format and/or future plans, please contact us!
- You can now calculate the standard deviation ('SD') on any parameter.
- When adding a statistic calculated on a parameter (e.g., mean, CV, SD), you can choose to add that statistic to all parameters, all fluorescence parameters, or all compensated parameters at once, by choosing those in the parameter menu of the statistics dialog.
- The order of the statistics in the Statistics Dialog window was changed to group them better.
- Printing: For batched outputs (either direct to printer, or printing from the Preview output), you now have the option to use the original pagination as defined in the Layout Editor. This means that you can print batch reports where each panel crosses page boundaries—for example, if you spread the page boundaries such that each iteration of the batch is on 3 pages, you will get 3 pages times the number of samples in the group for your output. To choose this option, select 'Use Layout's Pagination' where offered.
- Batched layouts are no longer grouped after being created.
- Keywords are better handled in layouts (particularly, for batched layouts and/or templates).
- When entering a keyword into a text box, you can select which sample for which to display the value (and single text boxes could have keywords from multiple different samples).
- You can now set the text style for axis labels differently from axis numbers (see Preferences); you can make the axis text as large as you wish and it will no longer be 'clipped' (see Bug fixes).
- There is a new contextual menu popup for when you click on a gate in a graph window that allows you to perform operations on the selected gate.
- The 'Create Manual Gate' interface has been extended to allow you to create a series of gates that are adjacent (non-overlapping) across the entire range of the displayed parameters. The series can be specified to step by equal channel numbers, equal intensity levels, or equal percentile levels.
- Gates and Graphs preferences were split into separate panels.
- A preference can be specified for how FlowJo exports histograms as graphs. The default is to export as polygons, which is useful for changing their characteristics; this works well in programs like PowerPoint. Deneba's Canvas does not interpret Mac PICT polygons properly; thus, changing this preference will cause FlowJo to export histogram graphs as connected lines. This makes it show up properly in Canvas (and other programs), but the histograms cannot then be filled in those programs (exporting of filled histograms will still work from FlowJo in all cases).
- Graph Sets can be defined in order to simultaneously open multiple graphs; these sets can be chosen from the contextual menu when you click on a sample or gate in the workspace.
- The text style for layout editor graph axes labels can now be defined differently than that for the axes numbers—you can have large axes labels!
- The location of FlowJo's Cache folder for transferring data from remote servers can now be specified to be either in the User's directory (default) or in the local shared directory. The latter is preferable for computers where User directories are kept on remote computers.
- The Preference for Hiding or Moving 'clipped' axes numbers has been removed (see bug fixes below).
- You can now zoom in and out of graphics in the SciBook.
- Workspaces saved with many SciBook entries now read in faster.
- A new option for Groups can be set ('Allow stain mismatch') that forces the group to add analyses and gates even if the stain names for the parameters are different than for the original sample's analyses.
- FlowJo now corrects the improperly formatted compensation matrix in Summit v4.0 data files.
- When files are moved and need to be found by FlowJo, you now have the option to ask FlowJo to perform an exhaustive search of all mounted disks for the data file (this may take several seconds).
- The text color for Print output headers and footers can be set in the Preferences.
- New quadrant gates will ignore the Preference for gate annotation position; the frequency will always be placed in the graph corners.
- The 'Edit Annotation' menu item has been removed (annotations can be edited by simply double-clicking on them in the workspace).
- If you misidentify a file that has been moved, FlowJo will show you the name of the file before asking you again to locate it.
- Layouts will now show at least one additional page, horizontally or vertically, when scrolling, to allow you to better place new objects.
- A new Preferences lets you use the Bi-exponential/Logicle transformation on uncompensated height parameters ('-H') in addition to the area parameters. Click on the button: Preferences->Workspaces->DefineÉ (32 bit options).
- Axes labels and numbers are no longer clipped in the Layout Editor or upon export to other programs. Finally! You can now have axes labels & numbers as large as you want!
- Layout Statistics Table tool doesn't crash if there are no samples in the workspace
- Overlaid histograms with auto-scaling have exactly correct Y axis values (previously, these 'relative' numbers were off by 4%).
- Text boxes in the Layout Editor can have braces in them again '{}'.
- Gate frequencies are not duplicated underneath the graph (after ungrouping an exported layout).
- Printing a specified range of pages from the Layout View now works (previously, would print all pages).
- Double-clicking in the workspace sometimes didn't open a graph; this now works. (Although if you double-click too fast, it may not).
- You can now delete a keyword value in the workspace and leave it blank.
- The Time parameter is properly retained on saved and re-opened workspaces.
- Italicized text in the workspace and Table output is better displayed on-screen (not clipped).
- A crash could occur if graphs and statistics were selected in the workspace, and the contextual menu 'Open graphs' was selected; this was fixed.
- Workspace mousing (click & drag, etc) is more responsive.
- Save As Template does not crash when the preference for incrementing workspace versions is selected.
- Occasional mis-sorting (or poor sorting) of samples fixed.
- No more unnecessary recalculations of subset gates that occurred in some circumstances (despite a Preferences setting of 'Only recalculate when needed').
- Concatenating events from different 32-bit data files (e.g., DiVa data) is now handled properly.
- Autogating will now place the resulting gate properly in windows that are not the standard size.
- Autogating tool is not active until the data has been loaded and displayed.
- Autogating will occur on the correct parameters after axes are changed.
- Boolean gates will immediately recalculate upon creation, if the Preferences are set for 'immediate recalculate.'
- Boolean gates work more reliably when copied from sample to sample.
- FlowJo will not crash if you choose to create Boolean gates on a group of selected items including Statistics.
- Possible bug causing crashes during gate adjustment fixed?
- Contextual menu for graphs & gates no longer appears for Platforms (causing a crash)
- Cell cycle and Proliferation platforms no longer crash if something happens to invalidate them during their computation (like a parent gate moving).
- Cell Cycle and Proliferation: Copy table to text will always work now.
- The 'Application Lock' contact information and hint information are no longer switched for new Lock commands.
- After batching a layout, the graphics are properly reset to the 'off' iteration state (previously, they were reset to show the first sample in the current group rather than their original state).
- Layout axes will now correctly adopt the color set by the Preferences.
- Layout overlay graphs will obey the specified background color (including transparency).
- Gate trees added by groups (i.e., when you add samples to a workspace) would not add an entire tree if any gate was based on parameters with stains that did not match the original; now only the mismatched gates are not added (unless the group option is to allow mismatches--see new feature above)
- Coulter '.HST' files are properly read and loaded.
- Cell cycle: The remove debris, remove doublets no longer crashes
- If a Boolean gate was opened without first opening the other gates, then the Boolean gate could show the wrong events.
- Fixed crash that could occur on very first use of autogate tool on first dotplot graph.
- Fixed: Opening graph sets places graph window below the menu bar.
- Fixed: Contextual menus in the workspace window show the platforms & Boolean gate options.
- Workspaces saved in version 6.0 cannot be opened with FlowJo v4.6
- The FlowJo icon is properly displayed on all workspace files (that have names ending in '.jo', '.ws', or '.flowjo').
- There are new “Help” menu items to provide quick links to documentation and contact information.
- Lists of FCS Keywords are sorted better, with user-defined keywords appearing first, and standard FCS keywords arranged in better order.
- The workspace auto scrolls to show the sample corresponding to the front-most graph window.
- The number of samples in a group is now shown in the first column after the name, not aligned with the 'Statistic' column.
- Template workspaces are now saved with the default extension of “.jot”.
- While editing a keyword value, you can paste a selection (copied from another program) that has a series of values (tab- or carriage-return-delimited, as from Excel). FlowJo will fill out successive rows with these values.
- You can now ctrl-click (or click-and-wait) on analyses in the sample list to show a menu of actions appropriate for the selected items.
- The column resizing button has been moved from the top of the workspace window to the middle bar.
- $PnE keywords (log/linear scaling of parameters) can now be edited.
- When sorting on keyword values, FlowJo looks to see whether a keyword value is numeric, alphabetic, or mixed, and sorts appropriately. For mixed values, FlowJo will sort “A-2” before “A-10” (even though this is not alphabetical); it recognizes the presence of both strings of letters and numbers and treats them independently when determining sort order.
- Graph windows now use the 'ctrl-click' (or click-and-wait) to show a menu to change the graph attributes (graph type, options, etc.), similar to the Layout Editor graphs.
- Cloning a graph window (“+” button, or “Open New Window” menu) now creates a new window that has exactly the same settings.
- You can specify (for dot plots only) the number of events to display, on a graph-by-graph basis.
- Compensation: When editing a compensation matrix, you can now copy it (to the clipboard) or print it.
- Cell cycle: There is a new preference to choose a Pulse Area parameter as the default for new analyses, and new preferences to control the default modeling characteristics.
- Cell cycle: The cursor coordinates are now shown in the window.
- Proliferation: The modeling algorithm has been improved to better find good fits. (The formula for the model has not changed, only the approach to the fit).
- Derived Parameters: Older derived parameters for Ratios, Gain/Offset are now automatically converted to Algebraic derived parameters with the correct formula shown.
- Derived Parameters: You can double click a previously-defined algebraic parameter to edit it.
- Overlay Legends: You can now click to select any row in the legend; press the 'delete' key to remove it from the overlay; drag to re-order the overlay.
- Show ancestry plots: You can choose to make all ancestry graphs show at equivalent size, rather than scaling them to fit in a single row or column.
- Text boxes: If you select a text box and choose 'Copy', then the contents of the text box are put on the clipboard so you can paste them into other applications.
- Arrows: If you create a line with arrow heads, you can now specify the shape of the arrow head to customize its appearance.
- Graphs: You can now specify the number of events to display (dot plots only) on a graph-by-graph basis.
- Graph Item Annotation: The dialog window in which you can specify custom contents for a graphic item annotation box now has a menu to choose keywords to insert into the annotation text. Also, graphic item annotations can be edited for multiple graphs simultaneously from the 'multi-item attribute editor' window.
- Batch Iteration Dialog: The dialog window that appears when you create a new Batch output has been made easier to understand; the iteration controls have been removed from this window (to specify iteration options, you must choose them via the 'Iteration options' menu item).
- Text boxes, annotations: In addition to specifying FJML commands for items like statistics ('
') and Keywords (' '), you can also specify information about any given subset using the 'Property' command. Properties that can be displayed include: 'Comment' (any comment in the workspace for that subset), 'GateName' (the name of the subset), 'SampleName' (the name of the sample), and 'Path' (the full gating path for that subset). For example, ' - Editing column names: While editing a column name, you can paste a selection (copied from another program) that has a series of values (tab- or carriage-return-delimited, as from Excel). FlowJo will fill out successive rows with these values.
- Hold down the option key while clicking on the 'Copy to clipboard' button and a transposed version of the table is copied onto the clipboard.
- Pulse-area parameter should be the default for Cell cycle analyses.
- Newly-created histogram overlays in the Layout Editor should be scaled to a fixed value by default (rather than scale-to-max).
- Specify the default line styles for histogram overlays.
- Default graph window size for newly-created graphs (brought back from Version 3.x of FlowJo!).
- Text traits for gate frequencies shown in graphs in the Layout Editor
- Text traits for headers and footers in printouts
- Specify the default statistic that is added to the Table Editor when a gate is dragged to the Table.
- Specify whether axis numbers, on graphs that are near the edge and would appear clipped as a consequence, should be moved slightly or hidden.
- Cell cycle platform preferences can be defined.
- Proliferation platform model display preferences can be defined.
- Suggested output file names are chosen better.
- Sample Information window can be resized to show keyword values better.
- Deleting a sample from the workspace will close its graph window.
- Create Value Series (while editing a keyword value) now obeys the maximum number of values to fill in, and better remembers the previous values you used for it.
- Cell cycle and Proliferation analyses immediately recompute a model if a parent gate changes.
- Proliferation: If create a constraining gate to position the undivided peak, you can now select it without having to close the window first.
- Layout graph items with oversized text (from the preferences) no longer randomly resize themselves. However, large text will still be clipped if it is too big. (You can choose to hide ticks or axis numbers to provide additional space for label text).
- Cell cycle: Remove apparent constraints that allowed positioning of peaks by absolute values (this was never a possibility).
- Cell cycle: Fixed synchronous peak constraints for DJF model.
- Cell cycle: copying analyses to groups or other samples retains the preferences for how models are displayed
- Workspace: Fixed editing a keyword value for workspaces with >1000 samples.
- Kinetics: Fixed an issue that could cause a crash for files with corrupt data at the end of the time series.
- Layout Editor: Multiple graphs dropped in from the workspace are now positioned better (so as not to overlap).
- Workspace column resizing no longer occasionally resizes the window height.

SUMMARY OF CHANGES SINCE 4.6.1
Important Notes:
Major New Features
Autogate tool. Point… click… gate. It shouldn’t be any harder. And, with FlowJo’s new Autogating tool, it can’t get easier! FlowJo’s autogating tool has an almost prescient knowledge of where you want the gate—an effect made possible by the instantaneous feedback of where the gate will be as you mouse over the graph! Choose the new autogating tool in the graph window, or simply hold down ctrl-option as you move the mouse over any bivariate graphic. (Note: if you hold down the mouse button as you click to create the gate, you can then track the mouse to inflate or deflate the gate to size it with even more precision!)
SciBook. The SciBook is a place where you can store pictures, text, tables, or custom annotations. The SciBook is stored with the workspace; you can use it as a permanent record of your analyses, as a temporary holding place for outputs, or just to keep notes for yourself. You can paste graphics, text, or tables from anywhere in FlowJo into the SciBook (the Graph window, Platforms windows, Layout Editor, Batch Layout View, and Table View all have buttons that will directly copy their contents into the SciBook). Contents in the SciBook do not change-therefore, if you change a gate, delete a sample, or make other modifications, the SciBook contents will not be modified. Once in the SciBook, you can copy into other programs, print, or simply just view. The SciBook gives you an interface to add comments about each item that you insert, and records the date and time that the item was inserted.
The SciBook is meant to evolve; we look forward to your comments regarding which features you use the most, what features you would like to see in the future, and what you do (and don't) like about it!
Backgating Analysis. Validating gate positions is one of the most important aspects of multiparameter Flow Cytometry. FlowJo now provides you with a tool to view the effect of every gate on your final gated population! In any graph window for a subset that is gated more than once, you can choose “Backgating Analysis…” under the Graph menu (or, click on the Backgating button that appears near the top right of the window). FlowJo shows you a window where each level in the gating hierarchy is displayed, with the final gated population overlaid at each level. This overlay is a backgating overlay: in other words, it shows what the final gated population would look like without that level’s gate! Therefore, you can quickly scan to see if any one of your gates is positioned incorrectly. The backgating display can be printed, copied, or saved in the SciBook (see below). Note that the Layout Editor can also show a version of the backgating analysis, by choosing “Show Ancestry” and selecting the “Backgating” option for a graph
Boolean gates. You can now create a gate which is a Boolean combination of any existing gates (i.e., 'and', 'or', and 'not' combinations). Boolean gates are 'live', meaning that they will reflect any changes to the gates on which they depend. FlowJo can also automatically create a series of Boolean gates that represent all combinations (plus and minus) of a set of gates. For example, if you have a sample which was stained on different parameters for IL2, TNF, and IFNg, you can create a positive gate for each of the three cytokines (for example, a histogram gate). Then use FlowJo's Boolean Combination to create the 8 gates that represent all combinations of expression of the cytokines (e.g., IL2+TNF+IFNg+, IL2+TNF-IFNg-, etc.). To create or edit Boolean gates, choose the parent subset(s) and select the menu item 'Boolean gates...' under the 'Platforms' menu.
Derived parameters. You may now create a derived (computed) parameter that is any algebraic combination of existing parameters. FlowJo allows you to specify arbitrarily complex formulas, and includes a wide variety of mathematical functions that you can use to transform the data. This platform can be used in FRET calculations to create a parameter that reflects the efficiency of resonance energy transfer.
Layout Editor: New Statistics Table. FlowJo now renders tables of statistics in a beautiful and highly customizable way in the Layout Editor. You can copy tables (either by dragging them from the Table Template Editor to use with Batch iteration, or directly from a completed table). Or, you can create them from scratch, adding your own statistics and keywords and other information. Statistics Tables in the Layout Editor come in two flavors: (1) Each row is from a single sample: this is like the output of the table editor, where statistics for subsets or the whole sample are all represented on the same row; (2) Each row can have subsets from the same sample: this allows you to view a number of statistics (e.g., MFI) on many subsets from a single sample in column format. Note that you can copy Layout Statistics Tables directly to spreadsheets (as tabular data) or to graphics programs (as their graphical representation).
Layout Editor:Overlay legends. The legends for overlays in the Layout Editor can now be customized to show statistics, keywords, or other pertinent information from each subset that is overlayed in the graphic. Simply double click on the legend to specify what should be shown.
Layout Editor: Iterate by 'nth' sample. Sometimes you just want to do batch iteration where the order in which you collected the samples defines how you want the output to appear-for example, every three tubes comes from a single sample, where the first of the three is a control, and the other two are two different panels. FlowJo lets you easily specify such a design by using the 'Iterate by nth' option. (Choose 'Iteration options' under the layout menu). In this example, you would iterate by 'every 3rd sample', telling FlowJo to group tubes into samples of 3. This significantly simplifies batch operations. All new Layouts are created with the “Iteration by nth” (n = 1, i.e., every sample) by default.
Templates: Improved functionality. This 'Iterate by nth' Layout Editor feature also means that Template Workspaces that contain batched layouts will work well. A batched layout is now automatically defined to have the appropriate iterator (and discriminator) values; when you batch a layout over every sample and save it as a new layout, the new layout is automatically defined to iterate by 'nth', where 'n' is the number of tubes in the original batch.
In addition, sample identification is significantly improved in FlowJo. This means that Template workspaces will fill out layout graphs as expected-FlowJo tries very hard to overcome any ambiguities that might arise because of multiple samples fitting the criterion for a single graphic.

Manual gates are used to set gates by intensity or percentile.
To manually enter a gate from the Graph Window, select the desired parameters using the X and Y axes drop-down selectors, and then choose Manually Enter Gate from the “Graph” menu at the top of your screen (this can also be accessed with command + G on a Mac and control + G on a PC when the graph window is selected). The window below will appear for the selected parameters, with upper and lower bounds shown, as well as drop-down menus for changing the units of the range.

Figure 1. The Manual Gate Definition window.
The window shows the following:
●Parameter: The active parameter for the X- (top) and Y- axes (bottom) for the graph window in which you will create a manual gate are displayed at left.
●LowerLimits: This is a data entry box where one can enter a lower bound for the X-axis. When the “Make Quad Gates” checkbox is toggled, this field changes to reflect the horizontal center point of the quadrant gate as shown below:
Figure 2. Setting Quad Gates using the Manual Gate Definition window.
●Upper Limits: This is a data entry box where one can enter an upper bound for X- and Y-axes.
●X and Y Axis Select Units: These drop down menus are used to select among units of absolute intensity, or fluorescence intensity percentile for the manual gate. By default, FlowJo will display the minimum and maximum values. A description of these options is below. The units of range are intensity and percentile.
- Absolute intensity is the scaled intensity value displayed on the axes in FlowJo. When this option is selected FlowJo will create gate boundaries that align with the numerical scale on the axes.

- A percentile is the value of the intensity below which the specified portion of events occur. When percentile is selected, FlowJo will create a gate that includes events that have greater intensity than the fraction of cells specified by the lower bound but a lower intensity than the fraction of events specified by the upper bound. For instance, if a selected gate has a lower bound of 50 and upper bound of 100 (for percentile) FlowJo constructs a gate which includes the brightest half of all of the events. Likewise, a percentile gate of 0 to 5 results in a gate for the dimmest five percent of the events.
●Control Gate: This checkbox is used to define the created gate as a control. A control gate will adjust it’s shape on the initial sample based on percentile or intensity, but will remain constant if copied to other samples. For example, if a non-control gate made on a histogram is set with a percentile range of 0 to 5, it will re-size to include the lowest intensity bearing 5% of the cells on each file it is copied to. A control gate will reflect the position of the lowest 5% of the control sample no matter which additional samples it is applied to. Absolute intensity is the scaled intensity value displayed on the axes in FlowJo. When this option is selected FlowJo will create gate boundaries that align with the numerical scale on the axes. A percentile is the value of the intensity below which the specified portion of events occur. When percentile is selected, FlowJo will create a gate that includes events that have greater intensity than the fraction of cells specified by the lower bound but a lower intensity than the fraction of events specified by the upper bound. For instance, if a selected gate has a lower bound of 50 and upper bound of 100 (for percentile) FlowJo constructs a gate which includes the brightest half of all of the events. Likewise, a percentile gate of 0 to 5 results in a gate for the dimmest five percent of the events.
