Hi Bruce,
I found some comments from your deep in the archive on converting distance measured on the sphere to distance on the folded surface: http://www.mail-archive.com/freesurfer@surfer.nmr.mgh.harvard.edu/msg00251.h...
Is this still the case? And, will loading the ?h.area file in matlab and summing the .vol vector give you total surface area, or is there a better way?
Thanks! Mike
