Hi Doug, thanks for the info. If I run isxconcat-sess with -m pcc, I get only a pcc file as output. Should I put this into mri_glmfit as --y pcc.nii, or should I re-run isxconcat-sess without -m pcc? Thanks again, Caspar

Hi Caspar, just use -m pcc in isxconcat-sess and continue as normal with the group analysis doug

Hi Freesurfer Experts, I am trying to calculate group pcc maps for resting state functional connectivity analyses. Unfortunately, the walkthrough does not cover this.
I found several posts regarding this on the mailing list, but I am not sure which one is the right way to go:
There is -m pcc in isxconcat-sess (

and there is also fast_glm_pcc (e.g., http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg22648.html
),
however, the various posts on the later functional all seem to differ in how to properly use it.
This is in version 5.1. Please advise. Thanks, Caspar
