Hi Elizabeth

check out the help of mri_binarize. I think something like:

mri_binarize --all-wm --i aseg.mgz --o aseg.wm.mgz

should do the trick cheers Bruce

Dear experts, I need a binarized wm mask for my analysis. The wm.mgz volume includes subcortical structures so I would like to use the aseg.mgz volume. I was hoping someone could give me instructions (command-line) on how to binarize aseg.mgz so that the wm=1 and everything else is 0.

Thank you in advance for your help!
