Hi,
I have a question about a probabilistic segmentation of gray matter with freesurfer. How can I do it?
if I binarize like this:

mri_binarize --i aparc+aseg.mgz --min 999.5 --o ctx.mgz

I obtain only a mask 0-1. Can I obtain a probablistic map like I obtained with SPM and FSL of the gray matter?
thank you in advance
