getting surface area based on FMRI ROI in SUMA?

hello, i have an FMRI ROI which is aligned with my SUMA surfVol in my freesurfer SUMA directory (it matches well, i was able to visualize the correlation map on the cortical surface in SUMA).

i was wondering if its possible to use SUMA/AFNI to actually compute surface area within my aligned FMRI ROI (right now its correlation values, but i can easily binarize it).


These programs provide some variations on this:


If the regions came from FreeSurfer segmentation, there should be files in the stats directory like this one with surface area for each region: stats/lh.aparc.DKTatlas.stats
