I don't have exactly what you are after but I do have some code that
will take as input a series of raw diffusion images, a bmatrix and a
deformation grid. As part of the tensor calculation it will permute
the bmatrix to suit at each point. I would argue that this method is
more "pure" but in 99.9% of cases rotating after the tensor
calculation will get the job done.

it's in the BIC CVS at minc_dev/mincdti/mincdti_EPI_dist.c  now would
be a good time to shift this to github but I haven't yet.
