we have a cluster that survived the Monte Carlo simulation for thickness, and we would like to obtain more data from that exact cluster (volume for example), is it possible to automatically create a label from that cluster? 

If I use mri_binarize or mri_cor2label is not working (I understand that the clusters are not stored as individual vertexes in the .mgh file but I don't know what the format is.

Thanks in advance!

PD: I am on a VPN and tksurfer is not working for manually creating a label with the contour of the cluster.
