Hi,

Thank you so much for helping me with my previous question!

I have downloaded from LONI's ADNI study the aparc+aseg.mgz files of ~3K subjects. Now I want to extract binary masks for the brainstem, lentiform nucleus (putamen + GP), and hippocampus from aparc+aseg.mgz files. What command should I use to do that? 

Thank you,

Arman
