1.15.1 Changes

• Improved phenix.map_to_model behavior

New and improved tools

• New algorithm for phenix.map_to_model is faster and builds longer chains
• phenix.trace_and_build can build protein into maps at resolutions as low as 4.5 A
• phenix.fix_insertions_deletions can build models in places where the map is poor
• phenix.refine_ca_model for optimizing C-alpha only models
• phenix.comparama for generating Kleywegt-like plots that show how residues moved in the Rakmachandran plots before and after refinement
• eLBOW can find unique instances of a ligand from the PDB and optionally create Polder OMIT maps
• Updated structural library for phenix.structure_search
• Updated ligand library for phenix.ligand_identification
• Improved reporting of cis-peptides for residues with altloc atoms

• Updated mmCIF support (stuct_conn loop, ligand restraints, sequence)
• phenix.refine, phenix.real_space_refine, and phenix.pdbtools will also output models in mmCIF format by default
• Dependencies are now based on conda packages, which will be more compatible with new operating systems and will improve consistency across all platforms (macOS, linux, Windows)
• Bug fixes

Reorganization and addition of cryo-EM tools
