Hi Joe, I added this option with a high expert level: use_statistical_model_for_missing_atoms = False .type = bool .expert_level=2 so it's not too visible at the moment... I'm still working on it. This will be a way to explicitly account for missing atoms in severely incomplete models. I will write a quick notice on phenixbb once it is available for general use. Pavel.
Hi All,
Does it make sense that when the box for "use statistical model for missing atoms" is picked under the GUI's "Global refinement parameters options" that one might obtain "better" Free-R values? I seem to be seeing that for a 2.3 A refinement of a crystal with a monomer of 550 residues in the asymmetric unit and 68% solvent content. When I uncheck the box I get about a 3% increase in Free-R. Is there more information about what this option is actually doing and when it might be useful to employ?
Joe
