Refmac will not introduce a repulsion unless the sum of the occupancies of the two neighbouring atoms id > 1.00 . Is that the case for you? ( It might list the close contacts - but shouldnt use them) If you want a link between the ligand and something else though you must label them both A or B

[ccp4bb] Problem with VDW restraints in Refmac

2007-08-16 Thread Alastair McEwen
Dear all, I am refining a structure with a partially occupied ligand. The binding site contains a Glutamine residue with a dual conformation with the ‘B’ conformation overlapping with the ligand. I have named the ligand ‘ALIG’ but when refining, Refmac notes a number of VDW deviations and th
