Thanks for your comments. They helped A LOT!!!!
I have a question about program SurfClust. What I want to do is find the maximum node in a cluster in an ROI. I know you can draw ROIs in suma although I don't know how at this moment. I was wondering that it seems you can output an ROI but not input one (unless I am wrong). We were thinking about inputing a parcellation from the human brainnetome atlas (which is brand new) and finding the largest node in this parcellation in hopes to get the corresponding coordinates in Volume space for each subject and averaging over subjects to get the "best" position in the brain region.
If you have any advice on the subject I would be very appreciative.
