![]() ![]() ![]() Once you press OK, the compensation settings for any plot on your layout to which this compensation was applied will be changed to the new values. If the Compensations window is open and displaying the compensation currently being edited, the Compensation Matrix and Spillover Matrix values will update in real time, as will plots to which the compensation has been applied.Ĭlick Cancel to reject the compensation changes and exit the dialog, or Restore to discard the changes but continue editing the plot. If you check Automatic Preview, the plot will update with the new compensation settings as you edit the compensation in real-time. Move the slider to either increase or decrease the amount of compensation. Use this dialog to compensate the two parameters against each other on the plot. If you would like the uncompensated always overlaid by default, check this box in the preferences.Figure 9.11 Creating a New Compensation from a 2D PlotĪfter naming a new compensation and clicking OK, or selecting a compensation definition to edit, the Edit Compensation dialog will appear (Figure 9.13). Overlay uncompensated – The matrix editor will allow you to overlay your uncompensated data on top of the compensated to view the difference. If you prefer to not see this confirmation box, uncheck the box here in the preferences. These preferences can be very useful since you have the control to set the default values of whatever keyword you wish to automatically assign compensation single stain controls to the compensation group upon loading the files! Matrix EditorĬonfirm Edit – when you click the “Edit” button in the matrix editor, a confirmation box will open asking you to confirm that you wish to edit the matrix. Some other common keywords are “TUBENAME” and “SampleID”. If you prefer to use a different keyword, you can remove the default $FIL strings using the X icon next to them in this interface and then click the “Add” button to add whatever keywords you would like to use. As we show here, the SSM is a useful indicator of instrument performance. The above image shows an example of two samples with the same panel using the same compensation matrix but stained and run on the cytometer on different days. Compared to the compensation/spectral overlap matrix1, the SSM provides independent information about measurement performance. The aggregation of all SS values together in a matrix is termed the spillover spreading matrix (SSM). Compared to the compensation/spectral overlap matrix 1, the SSM provides independent information about measurement performance. The aggregation of all spillover spreading values together in a matrix is termed the spillover spreading matrix (SSM). Thus, any FCS files put into a workspace that contains the text “comp” or “unstained” in the $FIL, or filename, will be included in the compensation group in your workspace when loaded. Here we derive an intrinsic measure of SS. Here we derive an intrinsic measure of spillover spreading. because FlowJo will not be able to calculate a compensation matrix for parameters not held in common across all control samples. The default values set are “comp” and “unstained”. The Compensation Wizard in FlowJo is one of the most frequently used platforms, and by extension potentially the greatest source of confusion on a per-cytometrist basis. $FIL – is the FCS file keyword for the name of the data file written by the cytometer. The “Group Inclusion” can be used to make files with certain file names get automatically included in the group when they are loaded into FlowJo. Select the Compensation button in the Preferences tool to open the Compensation preferences. If you run into this error it's usually due to. If you run into this error its usually due to.
