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.

Could you please tell me which are the parameters used (internally) in mri_gtmpvc when computing pvc, in order to replicate the same output when using mris_compute_volume_fractions??

Thank you in advance for your help!
