Hi Everyone, recently I had to update or do from scratch my talk "slides" on various subjects such as crystallographic structure refinement, maps, validation and some general PHENIX overview. Since I spent pretty significant amount of time making all these "slides" , ... I was thinking that may be this might be of use for some of you, so here it is... - 42 pages of general introduction to structure refinement: http://www.phenix-online.org/presentations/latest/pavel_refinement_general.p... - 45 pages of phenix.refine overview (including extended details about its use from the command line): http://www.phenix-online.org/presentations/latest/pavel_phenix_refine.pdf - 42 pages of "Some Facts About Maps": http://www.phenix-online.org/presentations/latest/pavel_maps.pdf - 50 pages of "Crystallographic Structure Validation": http://www.phenix-online.org/presentations/latest/pavel_validation.pdf - 31 pages of introduction to PHENIX: http://www.phenix-online.org/presentations/latest/pavel_phenix_intro.pdf Most of the slides in "Introduction to PHENIX" came from Paul Adams, Tom Terwilliger and Nat Echols. Thanks Nat and Jeff Headd for providing with interesting examples of structures with unusual geometry. All the best! Pavel.
