[HCP-Users] Inaccurate b0 Image from DTIFIT

Hello all - I am working on running DTIFIT on human connectome project diffusion data, but when I run the code using the gradnonlin option, the b0 image doesn't look correct. On a typical b0 image, the ventricles should be bright. The output on all of my subjects gives me dark ventricles.
