yes, run mris_preoproc with --meas volume, then surf2surf. Then run

mri_segstats --i lh.volume.mgz --exludeid 0 --seg ocn.mgz --avgwf avgwf.dat --accumulate

where lh.volume.mgz is the output of rerunning mris_preproc above
ocn.mgz is the ocn file which is output from the cluster analysis
avgwf.dat will be a number of subjects by number of clusters matrix with the volume foreach subject/cluster combination

Hi FS developers,

I ran mris_preproc, surf2 surf and glmfit and cluster analyses (monte carlo) for a surface based thickness group analysis. I am trying to extract volume measures from the same significant thickness ROIs. Is there any way to do this? Thank you!
