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

Re
If you use REST choosing ROIs, inputting covariables and performing the functional connectivity, then ROI_FCMap_ file represent the time course before the covariable have been regressed out.
If you want to acquire the time course after the covariables have been regressed out, you can try DPARSF. There is an independent option called remove the effects of nuisace covariates. After this process, you can perform funtional connectivity without inputting covariables and get the the time course after the covariables have been regressed out.
