I'm not sure what you are trying to do. If you want to look at
differences in surface area, wouldn't making all the ROIs the same size
defeat the purpose?

Hi Freesurfer colleagues,
I want to analyze regional profiles of differences in cortical surface
area (SA). However, SA and its group differences in SA depend on
parcellation size. In order to mitigate this effect, should I create a
parcellation that has roughly equal area per ROI in FSaverage space,
or equal number of vtx per ROI in FSaverage space.
Looking at smaller ROIs than the DK atlas - so I will be making the
parcellation in any case.
Thanks - any advice would be much appreciated
Yash
