Hi FreeSurfer

I need the white matter segmentations, and I've looked at some e-mail correspondence and one answer I think I can use is the following:

If you just want white matter, then better to create a mask from the

aparc+aseg.mgz with mri_binarize with the --wm flag.

I just don't understand what it means.. I do have the aparc+asset.mgz, but what is a mri_binarize and  --wm flag? I don’t have FreeSurfer installed on my on computer.

All the best,
Leise.
