Hello Charles and other members of Xplor-NIH,
I am trying to refine a cyana output structure against RDC and NOE data
using xplor. This cyana pdb has already been converted into xplor format
using pdbstat. I am using modified version of refine.py script that has
floating Da and Rh while running the structure calculation.
The output error message that I am getting is :
