Re: [Freesurfer] Qdec - ROI - different thickness results

sorry, I should have said mri_label2label, not mri_surf2surf doug

right, qdec shows healthy (X) > patients (Y)

mris_anatomical_stats show: Y > X

but I didn't do mri_surf2surf, I just copied the ROI.label in every subjects /label/ directory.

Thank you for your help Doug !

Have a great day,

Alex.

blue means that X>Y. So that sounds like it is compatible with
your ROI results, yes?
