[PyMOL] Optimize plugin throws "NameError: global name 'ob' is not defined"

[Douglas H. <Dou...@ed...>]

Hi all,

I installed Optimize.py, now when I start Pymol I see:

"Optimize plug-in needs openbabel to be installed in your system,  
please follow the instructions at
http://openbabel.org/wiki/Get_Open_Babel"

If I try to use any optimize commands I get:

"PyMOL>minimize all, nsteps 2
Traceback (most recent call last):
   File  
"/usr/people/douglas/programs/pymol-v1.7.2.3/modules/pymol/parser.py",  
line 254, in parse
     self.result=apply(layer.kw[0],layer.args,layer.kw_args)
   File  
"/usr/people/douglas/programs/pymol-v1.7.2.3/modules/pmg_tk/startup/optimize.py", line 237, in  
minimize
     obconversion = ob.OBConversion()
NameError: global name 'ob' is not defined
"

Open Babel IS installed on my system (v2.3.2), do I need to tell Pymol where?

cheers,
Doug
