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 doug

Dear all,
I've created a custom '.mgh' file containing values on the cortical surface using mri_vol2surf. I would like to compute some statistics on this surface in the aparc-areas computed by freesurfer. Can I then just use mri_anatomical_stats with option -t specifying the custom mgh file as 'thickness' input? Or does mri_anatomical_stats something more complex than just averaging the values inside each region?
Best, Martijn
