<onlyincludesection begin=description/>
This is a major bugfix release. System and unit test bugs in the Mac OS X application have been eliminated, the RMSD related functions for systems with old Numpy versions installed have been fixed, the system information printout when the relax path contains spaces now works, Python 3 fixes have been made throughout, problems with the last steps of the model-free auto-analysis under certain conditions have been resolved, and the [http://www.nmr-relax.com/manual/value_write.html value.write] and [http://www.nmr-relax.com/manual/value_display.html value.display] user functions no longer present a list of zero values when very small number are encountered (for example the field-strength independent ''R<sub>ex</sub>'' values from a model-free analysis). Upgrading is recommended.

Version 2.2.4
(17 March 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.4
<section end=metadata/>
== Features ==
<section begin=features/>
* Creation of the [http://www.nmr-relax.com/manual/structure_create_rotor_pdb.html structure.create_rotor_pdb user function] for creating representations of the rotor frame order model.

<section begin=changes/>
* Updated the release checklist document to include the correct instructions for minfx and bmrblib. These are the packages bundled with relax (http://gna.org/projects/minfx/ and http://gna.org/projects/bmrblib/)
* Improvements for Python 2 and 3 compatibility. Much of the Python 2 verses 3 compatibility, as well as different Python 2 version compatibility and different Python 3 version compatibility, code has been shifted into the compat module. The different parts of relax now import from the compat module for modules/packages with different import semantics for different Python versions. In addition the different handling of the bz2 and gzip module for reading and writing files has been shifted from 'relax_io' into 'compat'.
* Created the internal structural object MolContainer.last_residue() method.
* Fully implemented the structure.create_rotor_pdb user function. For this, the generic_fns.structure.geometric.create_rotor_propellers() function was created.

== Bugfixes ==
<section begin=bugfixes/>
* Fix for the system tests in the Mac OS X application binary. The Mf.test_bug_20563_missing_ri_error system test fails in the Mac OS X application binary. The problem is that the py2app extension used to build the Mac application decides that empty directories are not to be included in the app, so naturally the test fails when checking for these. Now empty results files have been added to these directories to trick py2app to include them.
* Fixes for the unit test package __all__ list checking. Now only *.py files and directories are checked. In some cases other files could be present in the packages, for example the object files when compiling the C modules. These would cause the unit tests to fail unnecessarily.
* Fix for the value.write user function for very small parameter values (Rex for example). This was reported by Martin Ballaschk <ballaschk att fmp-berlin dott de> in the thread http://thread.gmane.org/gmane.science.nmr.relax.user/1397/focus=1402 and by by Angelo Miguel Figueiredo <am dott figueiredo att fct dot unl dot pt> in the unrelated bug report at https://gna.org/bugs/?20613. The formatting string "20.15f" has been changed to "20.15g" to allow Python to decide if the normal decimal or exponential form of the number should be printed.
* Fix for a strange and extremely rare typo bug in the model-free specific analysis code. This was identified by Manish Chaubey <manish dott chaubey att tuebingen dott mpg dott de> in the message at http://thread.gmane.org/gmane.science.nmr.relax.user/1422. This only occurs if a relaxation data error of zero is encountered and is a bug in the RelaxError message explaining the problem with the data.
