[phenixbb] Maintaining the sugar puckerings

Hi all,

I have a protein-DNA structure at 3 angstroms that I have been refining
with refmac5. I have recently started to look into using phenix.refine
instead. However, I am still having some problems with the sugar
puckering of my DNA which is an ideal B-DNA and should be kept
C2'-endo, but keeps changing to C1'-exo or C3'-endo after refinement
with phenix. I have looked at the .cif files for the DNA and may update
the restraints. Is this the easiest way to go about restraining the
sugar puckering? 

Thank you,
Yu Seon Chung
