The Phenix developers are pleased to announce that version 1.7 of Phenix is now available. Binary installers for Linux, and Mac OSX platforms are available at the download site: http://phenix-online.org/download/ Some of the new features in this version are: Graphical Interface ------------------- - Simplified AutoMR interface for single-component searches. - Multi-criterion validation kinemage display in KiNG. - Validation of RNA, isotropic ADPs, occupancies. - Improved project management interface, which will automatically import old projects to the new format when upgrading from a previous version of Phenix. - Integrated help browser on Mac with contextual help buttons embedded in program windows. - phenix.find_tls_groups available as part of the phenix.refine GUI. - Improved and expanded documentation for wizard and Phaser GUIs. Structure refinement -------------------- - A new fast real space refinement protocol, which can substantially improve poor starting models. - A fast method for automated identification of TLS groups (phenix.find_tls_groups). - Reference model, Ramachandran, and secondary structure restraints to improve refinement at low resolution. - Automated secondary structure restraint generation for non-Watson-Crick base pairs (using the Saenger classification). - Automatic support for D-peptides when using standard PDB residue names. Molecular Replacement --------------------- - A new command, phenix.mr_rosetta, which integrates molecular replacement, automated model building and Rosetta model rebuilding for difficult structures. - A new fast search method in Phaser for efficiently locating multiple copies of the same molecule - A new program (mr_model_preparation) for preparing models for molecular replacement, which automatically downloads related molecules based on a sequence alignment and runs sculptor. - Improvements to ensemble generation (phenix.ensembler), with an option to use secondary structure matching (using code from Eugene Krissinel). Ligand fitting -------------- - New tool for automated ligand fitting using previous structures of related protein/ligand complexes (phenix.guided_ligand_replacement). - Bug fixes and other improvements to phenix.elbow. Analysis -------- - Multi-criterion kinemages can now handle custom restraints (from a .cif file). - RNA model validation is now available on the command line (phenix.rna_validate). - Updates to phenix.model_vs_data, which now generates Sigma-A plots and more detailed ADP statistics.
