Dear Dhiraj, you may want to check our web service dnatco.datmos.org where you can also generate 3D constraints for refinement in Phenix.

But since the question was refinement related I thought it will be ok to ask on ccp4bb.

I am trying to refine the structure using phenix. do I need to turn off the DNA secondary structure restraints during refinement? Application of secondary structure restraints depends on the quality of the experimental data. The most basic parameter to consider would be a resolution. For lower-resolution SS restraints might help to keep a reasonable geometry of the structure. The bent DNA should also work fine with SS since they are restraining base pairs and stacking pairs which normally don't distort too much. P.S. There is a separate bulletin board for Phenix-specific questions: http://www.phenix-online.org/mailman/listinfo/phenixbb Best regards, Oleg Sobolev.
