Dear FS team,

My question is how I should extract the measure of pial surface area from a significant cluster after group-analysis. I performed statistical analysis in QDEC, choosing pial surface area as the measure. I found a significant cluster. Now I would to extract the surface area of this cluster from each subject, so that I can plot the group means.  But the numbers I got from the "cache.th20.neg.y.ocn.dat" file are quite small (mean centered at ~1). I am wondering how I should get the correct numbers from each subject.

thank you in advance

Karl
