The PDF version of the relax 1.3.16 user manual The relax 1.3.16 user manual


This is mainly a documentation release. The relax user manual has been significantly updated - changes include the expansion and completion of the model-free analysis chapter, addition of graphical user interface (GUI) screenshots and descriptions, a description of Gary Thompson's multi-processor framework, and general updates and improvements throughout. For those who install relax using the scons 'install' target, the pyc and pyo files are now properly created for faster startup. The Bruker Protein Dynamics Centre user function class 'pdc' has been renamed to 'bruker' because of Bruker's absorption of the PDC into the Bruker Dynamics Centre. These user functions, as well as the BMRB user functions, have been added to the menu system in the GUI. Finally a test suite bug triggered in the Fink relax installation has been eliminated. If you would like improved documentation or would like to use any of the other changes, please update to this version.


The new relax versions can be downloaded from If binary distributions are not yet available for your platform and you manage to compile the binary modules, please consider contributing these to the relax project (described in section 3.6 of the relax manual,


Version 1.3.16
(11 May 2012, from /1.3)


  • The scons 'install' target now creates both *.pyc and *.pyo files during installation - this should result in faster relax startup times.
  • The test suite now passes on the Fink relax installation on Mac OS X as the ancient and very dead PyXML module is now being detected and worked around.
  • Renamed the 'pdc' user function class to 'bruker' and removed all references to 'protein' - this is due to the Bruker absorption of the Protein Dynamics Centre into the Bruker Dynamics Centre announced at (Message-id: <>) by Dr. Klaus-Peter Neidig (peter dott neidig att bruker-biospin dott de).
  • Updates and improvements throughout the relax user manual.
  • Added a new section to the introduction chapter of the user manual for Gary Thompson's multi-processor framework.
  • Added screenshots and descriptions of the graphical user interface (GUI) to the introduction and all of the analysis chapters of the relax user manual.
  • The GUI and logging/teeing modes are now compatible with each other.
  • Expansion and completion of the model-free chapter of the relax user manual.
