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 I first divide aparc into a new parcellation, and then proceed dividing the new parcellation into smaller ROIs. However, this method yields very strange results, as some ROIs are and some are not divided according to textfile I've created. Do you have any idea why this is, and how to solve it? Thanks, Linda

Hi Linda
I think that's one too many constraints. Do you need it to be based on the original parcellattion? If not and a uniform parcellation will do you can use mris_make_face_parcellation.
cheers Bruce

Hi all,
I would like to make a fine-grained surface parcellation from aparc - let's say 500 labels, and I would like the labels to be more or less isometric. When subdividing the parcellation with mris_divide_parcellation, the labels become very stretched instead of isometric. Is there a way to get a different result?
Thanks!
