Hello Freesurfer Developers,

I am trying to generate a solid volume out of the lh/rh.pial-outer-smoothed file.

I was able to get just the surface in .nii format by using:

mri_surf2vol --hemi lh --surf pial-outer-smoothed --mkmask --reg mri/register.dat --o surfsmoothed.nii --template mri/T1.nii --subject BerA

I also attempted to use --fillribbon

mri_surf2vol --surfval $SUBJECTS_DIR/Berger_Andrew/surf/lh.pial-outer-smoothed --fillribbon --reg mri/register.dat --o smoothedfill.nii --template T1.nii --subject BerA
gdiagno = -1
ERROR: cannot recognize the type of /Users/mah.ali/freesurfer/subjects/Ber
A/surf/lh.pial-outer-smoothed

I am wondering what would be a good way to generate a solid volume out of the pill-outer-smoothed files.

Thank you,

Miao
