Matt,
I have a quick question about non-linear distortions that you mentioned. How
do these distortions manifest themselves? My FA color and lines look correct
and I do not see any irregular hyper intensities in other data. Also, how
would distortions affect the registration? Do you suggest that portions of
the brain volume might be stretched out/warped in the diffusion data and not
on T1? Is this is the case, then this would ultimately affect tractography
results as well.
Sincerely,
Anastasia
