Hi list,
I'm very new to PyMOL, so please be gentle. I use macPyMOL 0.98
I ran into a problem when trying to run what may seem like a very
simple script in order to create a movie that zooms into a ligand
binding site of a protein:
set ray_trace_frames, 1
set cache_frames, 0
set hash_max, 400
cmd.mset("1 x5")
for a in range (1, 5):
cmd.mdo(a, "move z, 10")
cmd.mpng("/frames/frame")
When I run this script, I do get 5 rendered png files, but they're
all the same. The move command does not get executed. The log reveals
the following:
PyMOL>set ray_trace_frames, 1
Setting: ray_trace_frames set to on.
PyMOL>set cache_frames, 0
Setting: cache_frames set to off.
PyMOL>set hash_max, 400
Setting: hash_max set to 400.
PyMOL>cmd.mset("1 x5")
PyMOL>for a in range (1, 5):

The file path in the Traceback obviously does not exist on my Mac.
Does anyone know what's going on here?
TIA for any advice. I really would like to get this zoom thing
accomplished.
