Hi Shane
you probably don't need cvs as it is more to extend the surface-based registration to the entire volume. Here you just need the surface-based registration I believe. Use mri_vol2surf to sample the FA onto the surface. After that it is identical to a thickness study

Thanks Dr Yendiki.
I am more interested to compare MD in grey matter regions by putting the MD on the surface, and then do a glmfit type of comparisons. Is that OK? Would you recommend me to smooth the data after spatial normalisation? I have also used the mri_cvs_register as described on the tutorial.

Hi DTI Experts,
Is it sensible to do comparisons of MD on the cortex surface like a normal cortical thickness comparisons between group? If the answer is yes, are there recommended on smoothing ?
DT_RECON has been completed in Freesurfer.
Thank you.
