[PyMOL] `selection` argument in load_traj

[brisvag]

Hi Thomas,

I see! Is it supposed to work with other formats too? Or at least, is
it planned to be expanded? I'm trying to switch to PyMOL to view
GROMACS `.xtc` trajectories, and this feature would be a great
addition.

Cheers,
Lorenzo

Hi Lorenzo,

You are correct, it's doing nothing for most trajectory formats. Only the 
implementation for AMBER .trj files uses it. It looks like it allows selecting 
a subset of atoms.

Cheers,
  Thomas
