[ccp4bb] REFMAC5 refinement: nucleic acid residues with bad geometry

REFMAC5 refinement: nucleic acid residues with bad geometry Hi All, I am in the final refinement stage of an X-ray structure of a protein-DNA complex, 2.3 A resolution, using Refmac5 (REFMAC 5.8.0267, CCP4Interface 7.1.018, Linux platform). I am confident about the space group, refinement steps,
