I want to create mask for the midbrain and the precentral gyrus.

I used FSV6 to do the reconstruction. Then I used the flag -brainstem-structures in recon-all to segment the brain stem.

How can I create one mask that include structures from wmpac.mgz and brainstemSsLabels.v10.mgz for instance

I want to use mri_binarize to create one mask contains the following labels

1024 2024 3024 4024 from wmpar.mgz and 173 from brainstemSsLabels.v10.mgz

Any advice you provide is highly appreciated.

Thanks

John
