[phenixbb] how to inhibit selectively undue H....O repulsion during refinement with phenix.refine ?

I can investigate this and see what can be done. For this could you 
please send me an example? I'll need PDB files before and after 
refinement, reflection data file, any ligand cif files if used and 
indicate atoms in question..

Thanks,
