The Phenix developers are pleased to announce that version 1.6.4 of Phenix is now available. Binary installers for Linux, and Mac OSX platforms are available at the download site: http://phenix-online.org/download/ Just some of the new features in this version (1.6.4) are: - GUI: - new interfaces for eLBOW, CIF to MTZ conversion, phenix.find_ncs, phenix.superpose_maps - new structure comparison tool (evaluation of multiple related structures) - supports execution of jobs on the Sun Grid Engine queueing system - maps for PyMOL now output in (smaller, faster) CCP4 format - display of sequence and secondary structure in wizards and validation - new wide-format windows for wizards and phenix.refine - many bug fixes - Automated model building: - phenix.autosol now much faster and improved model-building after density modification - phenix.phase_and_build (carries out an iterative process of building a model as rapidly as possible and uses this model in density modification to improve the map. Up to 10x faster compared to AutoBuild, but model quality is nearly as good) - phenix.build_one_model (quickly build a single model from a map and sequence file, or extend an existing model) - phenix.assign_sequence (carry out an improved sequence assignment of a model that you have already built. Uses the new loop libraries available in phenix.fit_loops) - phenix.apply_ncs (apply NCS operators to a single copy of a protein to create all the NCS‐related copies) - phenix.find_ncs (now supports identification of NCS operators from a density map) - phenix.fit_loops (two main algorithms now available - fit short gaps using a loop library derived from high‐resolution structures in the PDB, or build loops directly by iterative extension with tripeptides - phenix.refine: - reference model restraints (restraint dihedral angles to a higher resolution reference model) - alternate ideal angles for torsion definitions (preserves side chain rotameric states) - automatic flipping of incorrect N/Q/H rotamers - custom planarity restraints - hydrogen-bond restraints for Watson-Crick base pairs - reflections with Fobs=0 used in refinement - automatic optimization of mask parameters - map parameters now consistent with phenix.maps - new custom_nonbonded_symmetry_exclusions atom selection parameter to fine tune non-bonded interactions across symmetry axes - Phasing: - Option for Phaser likelihood scoring of substructure solutions in HySS - SOLVE converted to C++; FORTRAN compiler no longer required for Phenix compilation - Other: - KiNG kinemage viewer incorporated into Phenix - Real space refinement option in ligand fitting - B-factor sharpening option for maps For a full list of changes see: http://www.phenix-online.org/documentation/CHANGES Please note that there is a new publication that should be used to cite use of Phenix: PHENIX: a comprehensive Python-based system for macromolecular structure solution.
