[MINC-users] xfmavg and lsq6 transforms

[Gabriel A. Devenyi]

Hi minc-users,

I have successfully used xfmavg on lsq12 transforms numerous times with no
issues (and it runs great with pydpiper).

I recently tried to average some (very similar) lsq6 transforms and found
that the result is not at all what I expected, it is quite far off from the
inputs.

Do lsq6 transforms not satisfy the mathematical underpinnings of xfmavg or
is something else going on?

Thanks for your insight!
