Yes, it is MRS.
Attached is a screenshot showing a mask of the svs VOI overlaid on the structural. This is from Gannet MRS software that uses SPM12 to register and segment the VOI. I have the generated VOI.nii mask from the Gannet output - maybe I could use the mask as the registration input for Freesurfer?
Thanks, Alex

Hello,
I have been asked to provide tissue composition stats (%GM,%WM,%CSF) for an SVS VOI. How can I register the svs file to the Freesurfer-processed brain and extract these values?
Thanks, Alex
