you can create a label with just that vertex, then use mri_label2label to dilate it, then use mri_segstats specifying the label with --slabel, using beta as input (--i), and specifying the output as --avfwf. Run it with --help to get more info

External Email - Use Caution

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
