Many thanks John for your advices and the links.
 
An additional question: as said in my previous message, i can generate a *.pyg file, however this file gives a *tiff file with a low resolution 504X480. It is possible by using the with render command in VMD to generate natively a *.pyg file with a higher resolution, say 800 x 600 ? If yes, how ?
 
Thank you again for your help
 
Stéphane

Hi,
  You can write simple scripts to do this type of thing, you'll want to
look at the movie rendering example scripts here:
  http://www.ks.uiuc.edu/Research/vmd/script_library/

If you just want to be able to use ambient occlusion lighting, you can
actually do that much more easily using the built-in Tachyon renderer,
as described here:
  http://www.ks.uiuc.edu/Research/vmd/minitutorials/tachyonao/
and here:
  http://bionano.physics.illinois.edu/Tutorials/

Cheers,

Also, Tachyon works automatically with the VMD movie maker plugin
so you wouldn't have to write your own scripts.
