Dear experts, I have 2 questions: 1) I created labels for some ROIs on fsavgerage (qdec analysis). I got statistics from these rois for each individual subject (by map-to-subjects, etc.), but what I am now interested in is to know the size of the ROI on the group level (so on the fsaverage surface).
Following up on the recent post, I tried 'mris_curvature_stats' but it gives error if I dont specify the subject. I am not to familiar with different commands, perhaps there is another one that would work? 2) Is there any "golden standard" for the minimum p-value or minimum size of an ROI to be considered a significant finding? I expect this may differ quite a lot, depending on how strong the effects of a variable on cortical thickness can be expected. Still, if you could comment on this or refer me to some literature, I would be very grateful. Thank you a lot!
