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 (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg30456.html) 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
