Hi FreeSurfer experts, We calculated the differences with downsampled -fsaverage6- thickness data between our groups using 'PALM' on the vertex level and got .mgz files as overlays wit h log-p values for each contrast. Now, we would like to test the overlap. We computed a ratio of overlap through 'mri_compute_overlap' within log-p overlay files but it showed labels (-s option) such as unknown and white matter. Is there a way to differentiate vertices that are in cortical regions? And could this labeling be correct?

I can't tell from your description what you have done (or are trying to do). Can you elaborate?
