<onlyincludesection begin=description/>
This is a major bug fix release - all model-free users of [[relax 1.3.6|relax version 1.3.6]] must upgrade to this version. The fatal bug is that the prolate diffusion tensor when initialised with D<sub>a</sub> set to zero will be converted to an oblate tensor. Other bugs fixed include support for volume integration together with replicated spectra, the scipy dependency now bing optional, 32-bit GNU/Linux test suite fixes, and better support for the reading of old version 1.2.x results files. An additional feature is that the relax packages/modules can now be imported and used outside of relax.

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).

Version 1.3.7
(10 January 2011, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.7
<section end=metadata/>
== Features ==
<section begin=features/>
* Shifted the relax installation path variable from __main__ into the status singleton object, allowing relax modules to be imported outside of relax.
* Shifted the global relax debug flag from __main__.debug to the relax status singleton, allowing the flag to be defined even when imported from outside of relax.
<section end=features/>
== Changes ==
<section begin=changes/>
* Speed up of the relaxation curve-fitting system tests.
* The sample_scripts/full_analysis.py script has been renamed to sample_scripts/dauvergne_protocol.py.
* Shifted the status singleton instantiation to the import level in all modules, saving execution time.
* Big code cleanups in unit_test_runner.py.

== Bugfixes ==
<section begin=bugfixes/>
* Peak intensity errors can now be calculated when using volume integration and replicated spectra (bug #17457).
* Failure of the prolate diffusion tensor in model-free analysis - if the tensor is initialised with Da = 0, the tensor is converted to being oblate. This was introduced in relax version 1.3.6.
* Made the N_state_model.test_pcs_fit_zero_pos system test less stringent so it passes on 32-bit Linux.
* The model_free _model_setup() method should handle no model-free model being set when reading relax 1.2 results files (bug #17417).
