Changes

For this release, the Mac OS X framework used to build the universal 3-way (ppc, i386, x86_64) binaries for the stand-alone relax application has been updated. The relax application now bundles Python 2.7.8, numpy 1.8.1, scipy 0.14.0, nose 1.3.3, wxPython 2.9.3.1 osx-cocoa (classic), matplotlib 1.3.1, epydoc 3.0.1, [[OpenMPI|mpi4py 1.3.1]] and py2app 0.8.1. This should result in better formatted relax state and results files and give access to more advanced packages for power users to take advantage of.

= Download =

The new relax versions can be downloaded from http://www.nmr-relax.com/download.html. 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, http://www.nmr-relax.com/manual/relax_distribution_archives.html).

= CHANGES file =

* Created the very basic structure.com user function for calculating the centre of mass. This is to simply allow an easy interface to the pipe_control.structure.mass.pipe_centre_of_mass() function.

* Expansion of the REMARK section of the PDB file created for the internal structural object. This is visible when using the structure.write_pdb user function, as well as the many other user functions which create PDB files. The relax version as well as the file creation date are now recorded in the PDB file. This extra information should be very useful. Empty lines in the REMARK section improve the formatting.

== Changes ==

* Created the new lib.structure.files module. This currently contains the single find_pdb_files() function which will be used to find all *.pdb, *.pdb.gz and *.pdb.bz2 versions of the PDB file in a given path.

* Fix for the breakage of the relax help system. This was reported at http://thread.gmane.org/gmane.science.nmr.relax.devel/6481. The problem was that the TERM environmental variable was turned off to avoid the GNU readline library on Linux systems emitting the ^[[?1034h escape code. See the message at http://thread.gmane.org/gmane.science.nmr.relax.devel/6481/focus=6489 for more details. However the Python help system obviously requires this environmental variable. Now only if the TERM variable is set to 'xterm' will it be reset, and to 'linux' instead of the blank string ''. This does not affect any relax releases.

== Bugfixes ==

* Fixed the packing out of parameter tex for global analysis in model IT99. Bug #22220 (https://gna.org/bugs/index.php?22220): Unpacking of parameters for global analysis in model IT99, is performed wrong.

* Fix for bug #22257, the freezing of the GUI after using the free file format window on Mac OS X. This is reported at https://gna.org/bugs/?22257. This is a recurring problem in Mac OS X as it cannot be tested in the relax test suite. The problem is with wxPython. The modal dialogs, such as the free file format window, cannot be destroyed on Mac OS X using wx.Dialog.Destroy() - this kills wxPython and hence kills relax. The problem does not exist on any other operating system. To fix this, all wx.Dialog.Destroy() calls have been replaced with wx.Dialog.Close().
