Hi Everyone, I'm pretty new to Chimera, but I'm working on an animation project that requires quite a few proteins and molecules. To speed up the process, I'd like to create a batch converter/exporter script to do the following: Open a PDB file Generate a multiscale model at a specified resolution Export the model out as a VRML or OBJ file I think I can do this using a Chimera command file, but I was hoping someone could point me in the right direction for some of the relevant command line syntax. Is it possible to control the multiscale model tool via command line (I know I can launch the dialog, but can I change the parameters and execute)? Is there a reference somewhere for the command line parameters for the multiscale models tool? What is the command line export command? Where can I find an OBJ exporter (there are references to it in the mailing list archive)? Any help would be greatly appreciated. Thanks, Trent BTW - I have a suggestion for improvement of Chimera. Add a command history window (or modify the existing one) that echoes out the command line text that is equivalent to any command executed via the Chimera user interface. Maya has this functionality and it is wonderful for anyone who is trying to figure out how to script a process that they know how to execute via the various menus.
