It seems as though it is necessary for a column name (e.g., a channel) to match exactly the desc keyword in order for the function to work. I think a workaround would be to change the "desc" keyword in $P3 for all the flowFrame objects from "CFSE-FITC" to "FL1.H" But I do not know how to edit the files. I could do that on the original flowJo software, but I don't have it -- the FSC file was created on the computer in the core facility and I don't have access to it anymore. I tried to use my Terminal/unix commands to gsub(/CFSE-FITC/,"FL1.H") ... but that changed the file kind from Flow Cytometry standard data to a Unix executable file .... and then it was not readable by flowCore package. The only way to change it back to the appropriate file kind was to revert it (which removed the gsub command). Any help -- either with flowFit OR on how to change the desc from "CFSE-FIT" to "FL1H" .... would be much appreciated!
