Hi FreeSurfer experts,
I have a couple of questions regarding mri_segstats tool for an analysis on vertex-wise cortical thickness data. We are attempting to compare maximum cluster sizes among permutations. We are having trouble figuring out how to get the anatomical label for each cluster using the --slabel argument. We are also wondering if the difference between cluster sizes between mri_surfcluster and mri_segstats is due to partial volumes, and if so, how to correctly use the --pv argument. It suggests in the wiki page that mri/norm.mgz volume is usually used but I believe we need something surface-based since we are using thickness data.
Thank you in advance for any help you can provide.
Best, Daliah
