Hi Friends, I would like to use Python to perform operations equivalent to the following GUI operations; I'd like to be able to do this as a batch script (e.g., I don't want the Chimera GUI to appear because I don't want to have to close it.): 1) Open a PDB file (I know how to do this part). 2) Tools > Higher-Order Structure > Multiscale Models (this opens the MultiScale Models popup window). 3) Click on the "Make models" button. 4) File > Export Scene... (this opens the Export Scene popup window) 5) In the Export Scene popup window, select File type to be "OBJ [.obj]", enter file name "test.obj" 6) Click on the "Save" button. I have used Python to open a PDB file, and translate, and rotate it around before. But I don't know where to begin with selecting Multiscale Models' parameters. Any tips? Any help would be much appreciated. Thanks, --Jon
