ROI wise comparison text files

 Hello, 
I'm trying to run functional connectivity using ROI wise comparison between regions.  After detrending, filtering, choosing ROIs, inputting covariables and performing the functional connectivity, the program gave me the expected text files. Does the ROI_FCMap_  file represent the time course before or after the covariable have been regressed out? If it is before the covariables have been accounted for, is there a way to acquire the time course after the covariables have been regressed out?

Thanks for your help in this matter
