Well, the 'rotdif' action was developed with the aim of looking at the
rotational diffusion of an entire molecule in solution. You could I
suppose specify only part of a molecule to use when calculating the
rotation matrices, but I'm not sure how you would interpret the
results. The region needs to be at least 3 atoms large, otherwise
RMS-fitting doesn't make sense.
