Hello FreeSurfer Developers,

I am registering FA maps to T1 for a group of subjects with MS and in many cases the registration is poor for the anterior corpus callosum (attached), cerebellum, pons, and temporal lobe. I am using the following commands (FreeSurfer version 6.0):

bbregister \

--dti \

--reg diff2T1_reg.dat \

--mov eddy_corrected_b0.nii.gz \

--s subject_temp

mri_vol2vol \

--mov dtifit_FA.nii.gz \

--targ orig.mgz \

--o FA2T1.nii.gz \
--reg diff2T1_reg.dat

Do you have any suggestions for improving this registration?

Thank you,
Andrew
