Hi John, what you have found in FAQ is for the command line version of phenix.refine. In the GUI you most likely see something like """ Anomalous scatterer group (1) Atom selection : """ So you need to type atom selection string in "Atom selection : " prompt. It should select your CD atoms. Something like this element Cd or chain X and resname LIG and name CD For more examples of atom selection syntax see phenix.refine manual section "Atom selection examples": http://www.phenix-online.org/documentation/refinement.htm Let me know if you have any questions or problems. Also, you can send me a PDB file and I will reply back with the directions on how you should select your Cd atoms. Pavel. On 8/26/10 9:41 PM, John Rose wrote:
Hi,
I am refining my first structure (Cd-SAD) with the Phenix (GUI) and would like to refine anomalous f' and f". When i check the box, a menu appears and I have no idea of how to define the Cd atoms.
I looked at the help and FAQ and found this: refinement.refine.anomalous_scatterers { group { selection = name BR f_prime = 0 f_double_prime = 0 refine = *f_prime *f_double_prime So I thought the name should be input as CD in the gui but when I submitted the refinement I got an error.
Any help here would be appreciated?
Thanks,
John Rose
