[Freesurfer] PETsurf and mri_compute_volume_fractions

2017-09-29 Thread Victor Montal Blancafort
Dear FreeSurfer experts, I am trying to obtain partial volume fractions of a DTI volume. When using the PETsurf framework (mri_gtmpvc), I obtain a pvf.nii.gz volume with GM, WM, subcortical, CSF and Skull tissue % values. However, when running the mri_compute_volume_fraction, the output diffears.

Hi Michelle, it should work like this. I don't know if it was tested with the -3T and -mprage flags. You can try to omit these flags (for testing only). Also the SB017 has been processed cross sectionally before, right? For debugging, you can also look at the individual steps in the base pro
