Difficult to say without seeing the original data. Have you tried
visualizing the trajectory data? I suppose it's possible that the RMSD
to your reference is smaller than the printed precision but that seems
unlikely.
If there is something weird with your unit cell (e.g. from a prior
coordinate rotation with 'rms') it's possible the imaging is resulting
in bad coordinates. You could take away the 'autoimage' command to
check for this.
