<onlyinclude>This is another major bug fix release. Please upgrade to this version if you wish to use relax for reduced spectral density mapping as significant bugs in that part of relax have been identified and fixed. Other significant changes include this being the only version of relax which will run with Python 2.5, the addition of [http://www.nmr-relax.com/manual/grace_write.html Grace plotting abilities] improving the analysis of relaxation exponential curve-fitting, large simplifications for the user and automatic looping over iterations in the 'full_analysis.py' script [d'Auvergne and Gooley, 2007][d'Auvergne and Gooley, 2008], and improvements to the reading and writing of model-free results files.

<section begin=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).

=== Features ===
<section begin=features/>
* The Grace plotting abilities have been extended, especially concerning relaxation exponential curve-fitting.
* A sample script has been added to plot the difference between the measured and back calculated peak intensities.
* Automatic looping over iterations in the 'full_analysis.py' sample script [d'Auvergne and Gooley, 2007][d'Auvergne and Gooley, 2008b] is now possible.<section end=features/>
=== Changes ===
<section begin=changes/>* The 'full_analysis.py' sample script[d'Auvergne and Gooley, 2007][d'Auvergne and Gooley, 2008b] has been significantly improved with all user modifiable options shifted to the top of the script.* The default CSA value is now -172 ppm.<section end= Changes ==changes/>
=== Bugfixes === <section begin=bugfixes/>* The previous release had problems reading results files from relax versions [[relax 1.2.0|1.2.0]] to [[relax 1.2.9|1.2.9]], but now results files from all versions can be read ({{gna bug link|8248|text=see bug #8248}}).* The synopsis of the system/functional tests now says '''[ Failed ]'''full_analysisif one the tests fails ({{gna bug link|8682 see bug #8682]).* relax now works with Python 2.5 ({{gna bug link|9093|text=see bug #9093}}).py* The writing of the model-free results file, which failed under certain circumstances because of the 'heteronuc' and 'proton' sample script attributes, has been fixed ({{gna bug link|8996|text=see bug #8996}}).* The problem whereby there is data loss for deselected residues when using [http://www.nmr-relax.com/manual/results_write.html results.write] followed by [http://www.nmr-relax.com/manual/results_read.html results.read] has been significantly improved with all user modifiable options shifted resolved ({{gna bug link|8953|text=see bug #8953}}).* Relaxation data can now be read if deselected spin systems have a relaxation data value or error value set to 'None' ([https://gna.org/bugs/?9101|text=see bug #9101}}).* The fatal bug of the reduced spectral density mapping values being incorrectly calculated has been fixed ({{gna bug link|9238|text=see bug #9238}}).* When using the alternate model-free parameter set {S<sub>f</sub><sup>2</sup>, τ<sub>f</sub>, S<sub>s</sub><sup>2</sup>, τ<sub>s</sub>}, the incorrect functions were being called ({{gna bug link|9189|text=see bug #9189}}).* A second fatal problem in the top reduced spectral density mapping code, the heteronuclear frequency being overwritten by that of the scriptproton, has been fixed ({{gna bug link|9259|text=see bug #9259}}).* Another problem with relax and Python 2.5, because of the Scientific package, has been resolved ({{gna bug link|9390|text=see bug #9390}}).* The default CSA value XH bond length is now -172 ppmcorrectly set in the reduced spectral density mapping analysis ({{gna bug link|9562|text=see bug #9562}}).* The convergence test in the 'full_analysis.py' sample script was failing if spin systems were deselected (see {{gna bug link|9892}} and {{gna bug link|10022}}).<section end=bugfixes/>
