Hi Douglas, I actually solved it! So, if yours is the same problem, you need to change your bval and bvec file format. I used mricron to convert from dicom to nifti, then used the bvec and bval files it produced for me. What it gives as output doesn't match with tracula's format.
bvec file should look like: 0 0 0 0 0 0 0 0 0 1 0 1 -1 0 1 0 1 1 0 1 -1 1 1 0 bval file should look like: 0 0 0 1000 1000 1000 1000 1000 1000 If you adjust yours accordingly, it should work.
