[PyMOL] restricting selection to the current frame

[Matthew B. <mp...@pi...>]

Hi,
Is it possible to force a selection to only apply to the specific frame 
rather then across frames?
I'm running in to a problem where I have some (~40) frames from an 
explicit solvent MD that I want to look at. What I want to do is look at 
water molecules around a specific residue at each frame, but when I do 
something like, 'sele wats, byres resn WAT in <md_obj> within 6 of 
<residue of interest>', it ends up a majority of the waters in the 
system. I think that what it is doing is finding all waters that are 
with 6 A of the residue of interest in ALL frames, then selecting them 
in the current frame. Which is not the expected behavior.

 From what I can tell, there isn't a selection syntax for selecting the 
frame. Perhaps there is a setting for this that I couldn't find.

Any help would be appreciated including solutions involving VMD or 
custom scripts.

Thanks,
Matt
