Hello there, I am trying to see if MRtrix can accept the b value information as a full b matrix with gradient cross terms, as opposed to just entering in a series of b-gradient vectors and their related effective b-values. I am working with Bruker data and so have access to the full b matrix for every diffusion image set in the scan.

I assume that the full 3x3 b matrix cannot be derived fully from just the gradient vectors and effective b-values. I hope that is correct?
