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

Didn't that trick very successfully lower the R-factors of the completely wrong models that led to the Great Pentaretraction? Unless you have stunningly high resolution, beware. Phoebe At 10:13 AM 3/28/2008, you wrote: Some time ago I've heard about the idea of proposing an ensemble of m
