can you tell me where the chimera command "cd" python code is located?

It's in the doCd function in Midas.midas_text. Minus some error handling, the function is basically one line: os.chdir(tildeExpand(args)) tildeExpand is a function in the OpenSave module which does some fancy footwork to expand '~' to a user's home directory on Windows machines. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
