Hi Chris
if you can find the peak vertex you can create a single vertex label from it, then use mri_label2label --dilate N to create an approximation of an N-radius circle cheers Bruce

Dear FS experts
I`m interested in extracting beta values from a FSFAST analysis performed in the subject`s native space. The beta values shall be extracted from a circular label around the peak vertex.
How can you define a circular label centered on the peak to extract average stats (e.g. betas) from that label?
I`m aware how to create mask from the whole clusters in a given ROI saving them as labels and extracting stats. However I`m not sure how to define a circular mask or label.
Thanks in advance
Chris
