Following the co-reg of diffusion space to T1 space, are the bvectors reoriented in proportion to the degree of deformation?

When transferring diffusion data to T1-space, b-vectors are reoriented using the computed rigid mapping between the spaces. The non-rigid EPI deformation (used for distortion-correction) of the diffusion data does not affect diffusion encoding directions, hence is not used for reorientation of b-vectors.
