Hi, I contact you because users of the program STRAP for protein structures and sequences asked whether Chimera could be used within STRAP for visualization. Currently Jmol and Pymol are used for visualiziation. For example the results of 3D superpositions and the location of mutations can be viewed. But some users apparently prefere Chimera. My question is whether Chimera could be linked to STRAP as well. The most important point is, what mode of interprocess commmunication exists in Chimera. For example Pymol and STRAP are linked via the stdin/stdout streams. STRAP can send commands to Pymol and is notified when atoms are picked. STRAP uses the scripting language of Pymol to load proteins, create selections and rotate proteins. Could all this be done with Chimera in a similar way ? Best regards Christoph
