[Freesurfer] average cortical thickness&intrinsic curvature index

Hello, Freesurfer experts: We are extracting the average cortical thickness of each hemisphere for every subject using mris_anatomical_stats. We found that for one subject (attached below), the thickness measures are quite similar but the “intrinsic curvature index” differs drastically betw

[Freesurfer] problem of correction for multiple comparisons in sarfece based analyses

Dear Freesurfer users, Which is to most preferably correction for multiple comparisons when investigating surface based cortical thickness changes between groups in smoothed data. Furthermore subjects between groups are related in other words not independent from each other. It is not clear fo
