Correct. Also make sure to set --projfrac 0.5 to sample in the middle of cortex (or set to some other value depending upon where you want to sample)

Thanks Doug!

When you say sample onto the mni152 surface, you mean to use mri_vol2surf, correct?

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,
