[Chimera-users] Script for positioning particles according the coordinates.

Hi Alexander,

   By "particle" do you mean an atomic molecular model (e.g. PDB file)?  
Do you already know the desired rotation and translation for each 
particle?  Or do you want to calculate those fits?  What you want is 
probably possible but I need more details to give specific advice.  
Chimera is not memory efficient with its molecular models, so if your 
particles are proteins with several thousand atoms and you want to load 
300 of them, you will need a lot of memory (~2 Kbytes / atom).
