Hi All,

I use QDEC to compare two groups differences, find some regions with significant differences. Considering this regions as ROI, i want to extract the mean thickness of ROIs for every subject, then compute the correlation between mean thickness and some scales . My questions is : should I extract mean thickness from the individual space or the common space?

Any advice would be most appreciated
