Dear CCP4 users,


I am a beginner in this field. It would be kind of all of you if can help
me how to move ahead with my problem.



I have an output file from CNS of a binary complex (DNA-protein) and I am
trying to refine it with refmac5 (restrain refinement) and job is failing
with error messages (written below)



Before restrain refinement, I converted the CNS output file (pdb) from
Codconv of CCP4 to pdb format.



Thanks in advance

Vidisha
