It depends on how you do the transform back to native space. You can
view the roi on the volume in the native space to see whether it landed
in the right place and that the surface goes through it

Thanks, Doug!
I think we were probably going about this the wrong way. If I transform the ROI
from MNI space back into native space, will the following commands give the
proper cortical thickness extraction from native space?
mri_vol2surf --mov roi_in_native_space.nii.gz --out rh.roi_in_native
You are currently using 6 dofs (rigid registration). If you use --dof
12, it will get better. Having said that, nothing will make it that good
since this is a volume-based affine registration.

Can you be more specific about which step is failing and how you are
verifying the failure?

Hello,
We are attempting to extract cortical thickness values from a pre-defined ROI
in MNI space.
Originally, we had followed the instructions detailed here:
https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness
for extraction in MNI space, but now wanted to extract thickness
