First register the DTI to the anatomical with bbregister to create a register.dat file for each DTI (you can use the same one for FA and MD; for the "mov" volume, use whatever reference you used for motion correction). You can then run
mri_vol2surf --mov FA.nii --reg register.dat --projfrac 0.5 --hemi lh --trgsubject fsaverage --o subject1.FA.lh.fsaverage.mgh
Run mri_vol2surf with --help to get info about the arguemts

Dear Freesurfer developers,
I would like to perform an analysis that requires me to have all of my subjects surface based and diffusion data in the same space.
I have performed recon-all –qcache so that all my surface based measures are in fsaverage space.
I now would like to register the FA.nii and MD.nii images to fsaverage space as well.
Could you please provide me some command line examples to perform this? I am unsure if I should be using mri_vol2vol or /mri_/cvs_register.
Thank you for your support.
Best, Derek
