[Freesurfer] Projecting subcortical ROI to the cortical surface

External Email - Use Caution

Hello FreeSurfer users/developers,

I have a subcortical ROI that I want to project to the nearest cortical vertex (see screenshot). So far, I have used the command mri_vol2surf --mov subject/mri/lh.het.nii --reg subject/mri/transforms/talairach.lta --hemi lh —o subject/surf/lh.het.mgh to project these voxels to the nearest vertex on the cortex. I am not sure if this is the correct way to do this because using mris_anatomical_stats on the result does not produce any thickness file. Any help would be greatly appreciated.
