Dear FreeSurfer Team, I have an additional question about the ?h.sulc.
[mris_anatomical_stats can do this if you specify sulc as the "thickness" file] your explaination means that instead of the mris_anatomical_stats -l <specific label> -t *lh.thickness* -b -f <output values> <subjects> lh I can use these command with change the -t option: mris_anatomical_stats -l <specific label> -t *lh.sulc *-b -f <output values> <subjects> lh After then, at the output values the header 5. thickAvg (Average Thickness) value can show an average of sulcal depth vector value. Is it correct understanding? I appreciate your detailed explanation. Best Regards, Han. On Mon, Sep 26, 2016 at 12:34 PM, Bruce Fischl <fis...@nmr.mgh.harvard.edu> wrote: > 1.
