There is not one file for CSF or GM, but you can extract them from other files. Eg, mri_binarize --i aparc+aseg.mgz --ventricles --o ventricles.mgz mri_binarize --i aparc+aseg.mgz --gm --o gm.mgz You can use aparc+aseg.mgz as your brain mask

Hi Freesurfer experts:
I used recon-all all to in my MPRAGE image and I would like to know which file is the corresponding to the CSF (cerebral spinal fluid).
Also, which is the correct file to choose for the brain extracted image, because I see 2 files that can be: T1.mgz, brain.mgz , which one is the correct ?
Also for GM the file is aparc+aseg.mgz the correct file ?
Thanks a lot and have a nice day,
Aldo
