You might check out http://nmr.cit.nih.gov/xplor-nih/doc/current/python/ref/csa-methods-marvin.pdf (referenced from) http://nmr.cit.nih.gov/xplor-nih/doc/current/python/ref/csaPotTools.html > Do the simulation parameters in refine.py matter much? Is > there a script specifically designed for membrane proteins? please see eginput/assignFit/02refine.py in the Xplor-NIH distribution for an example.
