Hi, This idea was rejuvenated recently in the follg. work from 2007. I believe the article you are looking for is:
Ensemble refinement of protein crystal structures: validation and application. Levin EJ, Kondrashov DA, Wesenberg GE, Phillips GN Jr. Structure. 2007 Sep;15(9):1040-52. Regards, Debanu. -----Original Message----- From: CCP4 bulletin board on behalf of Lucas Bleicher Sent: Fri 3/28/2008 8:13 AM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] Model ensemble for x-ray crystallography Some time ago I've heard about the idea of proposing an ensemble of models (as in NMR), instead of a single model for x-ray crystallography structures. If I remember correctly, this idea has been published somewhere. Can anyone tell me what article is that? Lucas Abra sua conta no Yahoo!
