This might be enough transformation-but often isn't. When you then compensate these parameters (i.e., those that are already transformed), the compensated parameters by default will get the same minor transformation. FlowJo uses a single automatic transformation for these parameters. A minor transform is applied to the uncompensated data when users export as directed above from the BD FACSDiVaT because this export generates dataįiles that can have negative values for Area parameters. Note the Preference above, set to "Enable Transformation".ĭisplay Transformation (Bi-exponential Scaling)įlowJo can display data in order to show all the cells that are normally squished against the axis. This will add a small amount of negative to each axis in order to remove the picket fencing and bring the negative populations up off the axis. However, FlowJo shows all the data and transforms the way the data is displayed using Logicle

The BD FACSDiVaT software has an option to only show the top 4 decades on the plots - in order to avoid showing the picket fencing in the lower region. You can then make your own display choices in the area called Standard Log Conversion Settings. If you do not wish to use FlowJo's visualization aid, you can remove the check mark from Enable Transformation. If you have a workspace open, then the popup menu Add to list will show parameters collected in the files in that workspace. In the box to the right, you can type the names of selected parameters to always display as linear (for example, when doing Cell Cycle analysis, In the upper-most area, you can select which parameters should be shown with logarithmic scaling by default.

on the Workspace tab you will see Reading DiVa and other 32 bit Data Files. To change these Preferences, go to the menu FlowJo > Preferences. In log and both side scatter and forward scatter in linear format. Since data exported from the BD FACSDiVaT software (except FCS 2 files) is saved in linear format, the user must tell FlowJo in which format to display the data (log or linear.) The factory default FlowJo Preference is to show all fluorescence parameters To edit the Acquisition matrix, you must first createĪ new matrix that is a copy of the acquisition matrix, and then edit that. In order to replace the previous matrix, simply apply the new one to the data file. The Acquisition matrix can be edited or an entirely new matrix can be created and applied to the data files. The option key and click on the graph window axis pulldown lists and choose parameters without brackets
To look at the parameters uncompensated, hold Therefore, when you add the data files to a FlowJo workspace, they show up with a red bar beside them (indicating they have been compensated). Is referred to as the Acquisition matrix).įlowJo will apply the Acquisition matrix to the data files. If the data was compensated during acquisition, this compensation matrix is included in the data file (in FlowJo, it Import to FlowJoĪll data exported from the BD FACSDiVaT software (except FCS 2 files) is saved in linear, uncompensated format. FCS 3.0 data files from BD FACSDivaT Software v4.0 are in floating-point format and are fully annotated.
#Flowjo compensation matrix import upgrade
BD recommends that you upgrade to version 4.0, and has indicated that this is a free upgrade.īD FACS DiVaT version 4: - Export as FCS 3.0. Uncompensated data will not be transformed (but compensated will be). Then export as FCS 3.0, 18 bit resolution (262,144 channels). BD FACS DiVaT version 4.01: - export as Experiment - This format allows for the best transformed displays of uncompensated parameters however, very little annotation (stain names, acquisition time, etc) is included in the file.
