Thanks Doug. I can know visualize the resected area using freeview.

As the output of mri_vol2surf produces an overlay and not a surface, 
measurements of area or/and intersection with other outputs from 
mri_vol2surf are not possible using mris_* functions.
What is the best strategy to follow to be able to do simple measurments 
on these mri_vol2surf outputs ? Transform to surface, but how ?

Thanks in advance,

Christopher
