External Email - Use Caution Thanks Doug. I added --ribbon ribbon.gz to the mri_vol2surf command but the output was exactly the same as omitting it. I think mri_vol2surf automatically loads ribbon.mgz when I include the --subject sub01. Just for my understanding, why shouldn't they look exactly the same if all I'm doing is going from vol2surf and back (surf2vol) using the same ROI? I guess when I convert a volumetric ROI to a surface with mri_vol2surf I will lose volumetric information which I cannot recover with mri_surf2vol, is that right? Best regards, Sam
