Dear Doug, Thank you for your reply! The command results in ERROR: Option --slabel unknown. I could not figure it out from the options descriptions with other option i could use, so i need some help again...
Cheers & thank you! Aga

Try something like this
mri_segstats --slabel fsaverage lh path/to/lh.yourlabel.label --sum lh.yourlabel.sum
The 4th column of the summary file will have the Area in mm^2

Dear experts, I have 2 questions:
- 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?
- 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! Best regards, Aga
