I would probably run recon-all on the mni152, and then sample the MD map onto the mni152 surface, then use mris_apply_reg to map it to an individual.
Also, Thomas Yeo has some possibly-better tools to do this.

Hello FreeSurfer users,

I have a mean diffusivity map that exists in MNI152 space that I want to register to a subject’s anatomical space. In the end, I want to display the diffusivity on the subject’s surface. I want to ask if this is the correct way to do this:

1) bbregister --s sub-01 --mov ./MD.mni152.nii --reg $SUBJECTS_DIR/sub-01/mri/transforms/bbregister.dat --init-fsl —dti #create registration matrix

2) mri_vol2vol --mov ./MD.mni152.nii --targ $SUBJECTS_DIR/sub-01/mri/brain.mgz --reg $SUBJECTS_DIR/sub-01/mri/transforms/bbregister.dat --o ./MD.nii #register mean diffusivity map to subject space

Thanks in advance,
