Hi VMDers,

I've been writing python scripts to visualize 3N dimensional vectors (i.e.
molecular modes) as arrows attached to atoms. I've been having a lot of
problems with length distortions and after checking my code over several
times I think that the problem might be that I have assumed that VMD uses an
internal length scale that I am not. What are the units that VMD uses?
