I too am puzzled as to why you would want to do this. In terms of getting
improvement in the alignment across subjects TBSS is one way to approach
this. Another would be to use the fiber orientations in the registration
like these folks have done:
I don't know of a reference where someone has done this (though I would
be surprised if it is not out there), so just be aware of this if you
try to publish. The commands look correct, however, you may or may not
want to sample in the middle of the cortical ribbon (--projfrac 0.5).

Dear FS experts,
I would like to run surface based analysis using FA maps. I am not exactly sure
that what I am doing is totally right specially step 2 . I used the following
commands:
1. I registered the FA maps to T1 using the command: bbregister --s bert
--mov dtifit_FA.nii --bold
