Subject: extracting mask for basal ganglia, deep grey, and centrum semiovale
To: Douglas N Greve <freesurfer@nmr.mgh.harvard.edu>

Hello Experts, 

I did like to create a mask for basal ganglia, deep grey matter, and centrum semiovale. I know how to extract the mask for the first 2 (using aseg.mgz) however, how do I extract the last one. What mask should I use to extract the centrum semiovale? I don't want to include the cerebellar white matter. 

Thanks. 

Best, 

Paul
