You can map the segmentations (aseg or aparc+aseg) to the functional space with mri_label2vol, then run mri_segstats passing it the func space aseg and your input mgh file.

Hi Freesurfers,

I have functional activation files (.mgh) which I can overlay onto a subject's surface. Now I am trying to do a functional ROI analysis based on the annotation files, e.g. to get information about the mean activation in a specific area based on FS segmentations.

Does anybody have any suggestion on how to do this in a straightforward manner?

Thanks a lot.

Sandy
