Dear list, I am quite new in the use of freesurfer and I have two doubts. 1. I am studying the visual areas of the brain, but I do not know how to perform a vertex analysis within a ROI. I already know how to obtain thickness data on a ROI (either drawn by hand or labeled), but I would like to restrict the area of a vertex-analysis to my ROI (visual brain areas)
2. When performing a vertex-analysis, is it correct to include TIV (total intracranial volume) as a nuisance variable?
