Re: [PyMOL] Trouble making pictures in a script

Hi Michael

If the system is very big and causes the ray tracing to crash, try to
lower the hash_max setting. I think the default is 100. If the setting
is lower, it will be slower, but use less memory. (and vice versa :-)

All the best

Esben

 Michael,
 
 The -c option forces PyMOL to run in command-line-only mode 
 which means it doesn't have access to the OpenGL hardware 
 (used by cmd.draw and interactive graphics).  In 
 command-line-only mode, ray tracing (cmd.ray) is the only option.
 
 Cheers,
 Warren

  Hi,
  
  I have a Python script that sets a system up and then calls
  cmd.png() to render an image. I use it to process several 
 files at a 
  time, and there's no need to look at it while it's working, so I use
  
  pymol -qcr myscript.py
  
  to launch it. It works fine when I ray trace things, but if 
 I just set 
  the system up and call cmd.png(), I get this error:
  
   ScenePNG-WARNING: invalid context or no image.
  
  Calling cmd.draw() instead of cmd.ray() doesn't seem to fix things.
  Any ideas? Some of the systems are big enough that 
 cmd.ray() fails, so 
  I'd like to be able to find a workaround.
  
  Thanks,

[PyMOL] Trouble making pictures in a script

2007-10-25 Thread Michael Lerner 
Hi,

to render an image. I use it to process several files at a time, and
there's no need to look at it while it's working, so I use

pymol -qcr myscript.py

to launch it. It works fine when I ray trace things, but if I just set
the system up and call cmd.png(), I get this error:

 ScenePNG-WARNING: invalid context or no image.

Calling cmd.draw() instead of cmd.ray() doesn't seem to fix things.
Any ideas? Some of the systems are big enough that cmd.ray() fails, so
I'd like to be able to find a workaround.
