Hi Francesca,
why 82? Are you comparing by parcellation unit? The newer versions of tksurfer have false discovery rate correction built into it, you might try it out.

Dear Free-surfer Users: when comparing cortical thickness measurements between patients and healthy people by the means of independent -tests, would you recommend correcting by Bonferroni method and consider as significant a p-value given by 0.05/82 or going ahead and just forget about the correction? Any suggestion on that would be greatly appreciated.
Thanks!
