Re: [phenixbb] occupancy of a part of a ligand

Hi Pavel, I have a ligand (ADP or ATP) that partially lost the last phosphate group. Can I refine a group occupancy for the adenosine part of the ligand separately from the phosphate groups of this ligand. If I do atomic occupancies, they diminish for the terminal phosphate groups. I can imagine that I can refine them as two superposed ligands with different numbers of phosphates, but is it possible to do just different group occupancies for parts of the ligand? Maia
