Re: [phenixbb] Anomalous or not?

Charles, So if you have bound ligand with a covalently-linked Bromine, and the ligand isn't abundant in your unit cell, don't you *expect* the anomalous signal to be weak ? Have you tried a DANO model-phased difference map or something comparable ? Phil Jeffrey Princeton On 7/10/14 12:52 PM, CPMAS Chen wrote:

Well, let me make this clear.

1. I am using Br anomalous signal to identify the potentially bound ligand. 2. I do shoot the crystals at 0.92A. 3. the different crystals have different resolution, but anomalous signal was weak as reported by autoxds.
