I need to confirm if the steps below are correct, so I would like to ask freesurfer experts help. By using the Left-Cerebral-White-Matter mask imported from freesurfer as a seed I created a tract end points density image of the arcuate fasciculus in a NIFTI format (first figure). I want to display the image on the same subject’s white matter surface. So, I wrote the command as follows

mri_vol2surf --src DensityMAP.nii.gz --out filename.mgh --hemi lh --surf white --out_type mgh --regheader subject_id
