Re: [phenixbb] MR-SAD, Yb, combined phases

Hi Joe,

Second, when I do refine using the MLHL target function, I am finding quite a bit of excess positive density around the Yb sites. How do I try and account for this? I have attempted to take care of it with ADP and occupancy refinement but that doesn't seem to be enough. The resolution is 2.2 A and the anomalous signal is quite good (alas that is why I am also seeing the sulfurs clearly in the anomalous difference map).

see pages 8-14 here: http://www.phenix-online.org/presentations/faq.pdf Please let me know if it doesn't help! Pavel
