Dear Phenix Community,
  I tried to model two ligands one of which has two conformations. In other
words, the two scenarios are: 1) ligand X with conformation A (XA, 75%
occupancy); 2) ligand X with conformation B (XB, 25% occupancy) plus
another ligand Y. However, the problem is ligand Y will have steric clash
with ligand XA. If I rename ligand X and Y to the same residue name then I
do not know how to define the CIF file.
  I apologize if this question was asked before and I do not know how
Phenix or other refinement can deal with multiple conformation a group of

Happy new year!
