[Chimera-users] Recursive structure matching and acquisition of descriptive numbers

[Greg Couch]

Yes, Chimera's Python code is only "warrantied" to work with its own 
Python.  See question 3b of the Chimera Programming FAQ, 
https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html#q3b, for 
how to install other software into Chimera.  Other parts of the FAQ may 
help you too.


That said, Jaime Rodríguez-Guerra took my previous comments on this 
subject, 
http://www.cgl.ucsf.edu/pipermail/chimera-users/2015-January/010647.html, 
and came up with pychimera, https://pypi.python.org/pypi/pychimera. I 
haven't checked to see how it handles all of my caveats, and it can't 
completely without using a modified Python, but I suspect that it would 
be good enough for you.


     HTH,


     Greg
