I will note that I don't really know what others do with this information. Bob had posted this previous information on the computation.

It may be that it's good enough to just get an affine warp and nonlinear warp together. One way to remove effects of rotation and translation might be to do a rigid_equiv transformation separately. Then use that rigid_equiv output as input to another animal_warper. The first will remove effects from both rotation and translation. Scaling and shearing would be applied in the second iteration and the nonlinear warping. You could compare the results as one or two steps.
