Compensation Group

Tags:

Probably the first thing you’ll notice about the Workspace window changes is the new special Group “Compensation” :   FlowJo scans your files as you load them into the workspace, and if any of them match our criteria for compensation controls, they will be added to this group. You can see the default inclusion criteria for… Read more »

Compensation FAQ

Tags:

Can my compensation control be too bright? No.  In fact, the brighter, the better!  Compensation controls allow the software to calculate how much spillover fluorescence occurs from that level of primary fluorescence.  The equation calculates the ratio of the DIFFERENCE in the secondary fluorescence over the DIFFERENCE in primary fluorescence (essentially, a slope).  Therefore, any… Read more »

Applying and Removing Compensation

Tags:

This page captures some of the work flow gestures in the Compensation user interfaces in FlowJo. For more details, consider looking at our Compensation Tutorial or Work Flow. Assigning Control Tubes to the Compensation Group: This should happen automatically as you add data. Samples will be placed in the “compensation” group if they contain the phrase… Read more »

Univariate Hints

Tags:

This page contains suggestions for improving the fit of difficult to model cytometric data. Preprocessing Removing doublets, dead cells, and debris will improve the condition of data. Whatever steps you typically follow to do this can be applied to cell cycle data.  Some common methods for doing this are: Doublets can be removed by plotting… Read more »
