Hi Bruce, Thanks for your detailed explaination! I have one more question about it! Is it possible to get cluster size for being painted SPM results on freesure surface (like getting the cluster size of cortical thickness in QDEC )? Is there any command getting it?
Any idea will be appreciated! Thanks!
