Hi Bruce, Thanks for the suggestion. I've tried mris_make_face_parcellation, but I would still prefer the parcellation being based on the original. I'm now trying to use mris_divide_parcellation in multiple steps (to try and circumvent the constraint of dividing only by the longest diameter), where

Dear Experts, I have some related questions: 1) Am I right in thinking that the default settings for recon-all produce aparc files where the areas are based on white matter and not pia ? 2) Therefore am I right in assuming that when I use aparcstats2table across my subjects using "--meas area", t

ok, found it. It's very, very low contrast. What flip angle and TE did you use. I can't visually distinguish gray from white in many regions such as motor cortex, so I can't imagine that you can get good thickness estimates over much of the brain. You could still use them for functional analysi
