After finishing group analysis, how can i obtain the thickness value of each ROIs showing significant group-difference in fsaverage space? That is to say, how i get the value of each ROIs which have been normalized to the fsaverage template. The method suggested in tutorials page(
http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis) just tells the way to get the thickness values in individual space.
