Hi Eric,
 The scripts is not working.. It is giving me following error message.  Is
it possible to call the minimization step inside the script so that i can
use the bcc charges?
Thanks a lot for your help.

chimera --nogui x.mol2 script.py
Sorry: IndentationError: ('expected an indented block', ('script.py', 6, 8,
'residues = m.residues\n'))Opening x.mol2...Compiling script.py...Compiling
