Re: [Freesurfer] mri_anatomical_stats on custom 'thickness' file

It can do both. When you spec --annot, then it does it on the surface and you have to pass it surface data (which you already have since you ran vol2surf). doug

Thanks Doug for your quick reply. But mri_segstats computes the average value inside the cortical region in the volume, right? That's not wat I want to have, I want to know the average value of the data in the volume on the wm/gm surface (i sampled with projfrac = 0).

Any thoughts?

I would use mri_segstats and specify the --annot option
