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