[Elaine Meng]

Hi Brandon,
It doesn't make sense to try to use perframe to perform some multiframe action.  

Perframe is literally per frame (graphics redraw frame, not vseries timepoint or trajectory frame).  I agree it can be confusing that "frame" is used to mean these different things.  See Frames Terminology:
<http://rbvi.ucsf.edu/chimerax/docs/user/commands/coordset.html#framesdef>

I hope this helps,
Elaine
