Hi Dhivya
if you are doing it in the space of the anatomicals, then use identity.nofile as the reg file (which is a special file name that will internally create an identity matrix). The output stem is whatever you pick - it will be prepended to the files that are written with the volume fractions.

External Email - Use CautionHi,
I would like to get CSF/GM/WM segmentations from aseg.mgz or in other words from labeled brain. Can I do that with mri_compute_volume_fractions ? Also, I am not sure about the parameters to supply, <reg file> and <output stem>?
Could Someone point me to some documentation on how should use this function to get the segmentations ?
Thanks, Dhivya
