Hi Jacob
I don't think they currently are modified except to remove the mean, which is kind of arbitrary anyway.

Hi Freesurfer team, I have a quick question regarding the output of .sulc values in Freesurfer:
From previous messages on the list, it seems as though the .sulc values in each hemisphere are 0-median and unit standard deviation of the original mm sulcal depth. Is this correct? Namely, I'm wondering the best way to obtain vertex-wise values for raw sulcal depth (mm) from a subject's Freesurfer (recon-all) output. Perhaps this may just entail un-standardizing the .sulc values?
Thank you! Jacob
