Dear Ed,
These tables were reported by Refmac5:
Before refinement,
-------------------------------------------------------------------------------
Restraint type N restraints Rms Delta Av(Sigma)
.....
VDW repulsions: symmetry: refined_atoms 38 0.232 0.200
VDW repulsions: symmetry: others 100 0.393 0.200
HBOND: symmetry: refined_atoms 11 0.229 0.200
HBOND: symmetry: others 1 0.120 0.200
.....
-------------------------------------------------------------------------------
After refinement,
VDW repulsions: symmetry: refined_atoms 27 0.190 0.200
VDW repulsions: symmetry: others 76 0.262 0.200
HBOND: symmetry: refined_atoms 13 0.225 0.200
I thought that meant there's vdw repulsion energy among symmetry
related atoms, which I want refmac5 to ignore.
