What are the rotations?  very close to 0?  If so then I suspect you
are being bitten by the fact that there are a number of ways to
describe the transformation in an affine matrix with a set of
translations, scales and rotations.  However if you are only trying to
recover translation and scale this still should not happen.

Copy in what minctracc and param2xfm return (And what you entered) and
we'll go from there.
