        Hi, I am wondering what is the criteria for occupancy refinement of ligands. I noticed that R factors change very little, but the ligand B-factors change significantly . On the other hand, the occupancy is refined to the second digit after the decimal point. How can I find out the error for the refined occupancy of ligands? Maia
