To familiarize yourself with this interface, read this chapter.
Once you have a compensation matrix and wish to examine it, you will be using the Matrix Editor. The plugin can seek out the clusters based on the peaks in this plot, or the user can gate. reachability, reveals what is called a reachability plot. Plotting the resulting parameters, orderNum vs. If you acquired your data with single-stain controls and wish to compensate it using FlowJo, read this chapter. The plugin can then separate the events into clusters based on the results of the OPTICS algorithm run. The compensation matrix is represented by the grid to the left of the sample name.Find more FlowJo tuto. CHAPTER 2 – Creating a FlowJo compensation matrix from single stain controls Create new, apply old, or compare different matrices. If, for any reason, you want to alter the matrix values, read this chapter.
Another observation is that when setting voltages > in these channels we are having to increase the voltage over the initial > background level in order to see the positive.
#FLOWJO 10 MANUALLY ADD COMPENSATION UPDATE#
This keyword is read and data in the file are compensated when the data is read into FlowJo. When the experiment-wide compensation doesn’t match the compensation used for gating, there will be a war n ing message informing you to either update the experiment-wide compensation or redraw the gates to match the experiment-wide compensation before you are able to set up the FlowSOM run. >When putting these data into FlowJo and going in and manually changing >the compensation values to what he has seen historically everything looks >just as it always has. Many data files contain their own pre-defined compensation matrix keyword, which was written when the file was created. Then, after collecting the controls and performing compensation, when you are finally collecting your samples, make sure each one is labeled with the same name. CHAPTER 1 – Altering an acquisition matrix In Diva, when you create a compensation matrix, you can add additional columns of the channel in question, and label each one with the appropriate antigen name.
Poorly scaled data will effect downstream compensation, so get into the habit of adjusting transforms through the “T” button in FlowJo’s graph window, prior to opening the compensation wizard for single stained control assignment. Note, Compensation should always be preceded by scaling your data appropriately. FlowJo v9.7.7 When transporting CytExpert data files into FlowJo v9.7.7 the data appears as below: IC6. For your convenience, this document is broken into chapters. This page will help acquaint you with the various ways to interact with Compensation Matrices in FlowJo.
