2008

14th January 2008
Phaser-2.1.2 released
  • Download from this website and with phenix-1.3b
  • Patch to fix segmentation fault in non-linux executables

2007

12th December 2007
CCP4 Automated Downloads
A Phaser module is now available through the CCP4 automated Downloads page and from the Daresbury ftp server.
12th November 2007
Phaser-2.1.1 released
  • New Features Phaser-2.1.1
    • Default packing criteria relaxed to allow a small number of clashes
    • Default packing distance increased to identify intercalation of helices
    • Composition can be estimated from solvent content
    • Default composition corresponds to 50% solvent
    • If automated MR search finds some, but not all, components, the partial solution is output
    • Improved SAD phasing
    • SAD phasing starting from MR partial model
    • Output of PDB hybrid-36 atom numbers and col(21-22) chainids for largest structures

2006

1st November 2006
Phaser-1.3.3 released
  • Download with ccp4 6.0.2.
  • New Features Phaser-1.3,3
    • Filename parsing accepts quoted strings, for Windows filenames that include spaces. Change synchronised with corresponding changes throughout the rest of the CCP4 suite.
1st July 2006
Phaser-2.0 released
  • Download with phenix-1.24-beta
  • Minor Bug fixes from Phaser–1.3

    • R-factor reported by MR_RNP and MR_LLG modes (verbose output)
15th June 2005
Phaser 1.3 released
  • Download with Phenix-1.1a
  • New Features Phaser-1.3
    • Release with Phenix-1.1a
    • New Normal Mode Analysis of structures
    • New Cell Content Analysis Mode
    • Improved Automated MR
    • Map coefficients appended to input mtz file
    • Score stored in .sol file is Z-score rather than LLG
    • Final phasing and refinement to full resolution on mtz file
    • Packing of RNA/DNA
    • Packing to form close packed oligomeric complexes
    • Waters in pdb files excluded from packing
    • Only the most similar model in an ensemble is used for packing analysis
    • Reduced memory requirements
    • Composition/MW determined from sequence
    • Automated MR now available as a python script
1st June 2005
Phaser-1.2 expired
  • A typo in the expiry date in the source code caused the source to expire. A message explaining what happened and possible ways to work around it has been sent to all registered Phaser users. We apologise for the inconvenience, and we are working hard to get version 1.3 (which will not have an expiry date!) released as soon as possible.
