[Chimera-users] copy cmd in nogui script

[James A. Cleland]

Thanks to both of you for your input on this issue. I am currently using
Xvfb to run Chimera against a headless X server. I believe this is going to
work for my application.

Thanks again!
James

Hi James,
In general you can run chimera in nogui mode.  However, currently  
there are a few things that can only be done in the GUI mode - I am  
told this includes any image saving or exporting the scene (povray,  
renderman, OBJ, VRML, X3D).  Sorry about that,
Elaine

The only way right now to use the copy command in nogui scripts, is to use 
the "Linux 64-bit Off-screen OpenGL" version of chimera that you can get 
from the daily builds, 
<http://www.cgl.ucsf.edu/chimera/alpha-downloads.html>.  It is "headless" 
and uses the Mesa software OpenGL implemenation.  If you need a 32-bit 
Linux version, please let me know.  It's on my list of things to do, but 
at a low priority.
