Description

This is a major bugfix and feature release. Support for the programs Dasha, Modelfree and OpenDX has returned and XEasy and NMRView peak lists can now be read. Upgrading to this version is highly recommended as it fixes a number of very important bugs. Some of these are include faulty error analysis when performing relaxation curve-fitting, results.write failure, model selection failure if spins were deselected, diffusion tensor optimisation failure, and internal PDB reader problems.

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

Version 1.3.3
(29 November 2008, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.3

Features

Dasha can be run from within relax again.
Art Palmer's Modelfree can be run from within relax again.
OpenDX execution and control is once again supported.
NMRView peak lists are now supported.
XEasy peak lists are again supported.

Changes

Internal relax cleanups by the addition of the specific model_loop() method - this should eliminate a series of potential hidden bugs.
The results.write() and results.display() now only support XML output.
More information is now extracted from the Modelfree mfout files.
The version of the Modelfree program is checked and if it is an old, buggy version, relax will refuse to execute it.
The system tests can now handle the sometimes large differences in Modelfree results between the GNU gcc and Portland C compiler versions.
Fixes and improvements to much of the API documentation.

Bugfixes

A failure of the minimisation set() function has been fixed.
The reset() user function now works again.
Fixes to the relax data store methods add(), to_xml() and from_xml().
Many fixes for the support of Art Palmer's Modelfree program.
The mapping of the global parameter space (diffusion tensor, etc.) for visualisation in OpenDX has been fixed.
state.save() no longer fails after running state.load() (bug #12437).
Sparky peak lists with the assignment '?-?' are now handled properly (bug #11913).
Error analysis in relaxation curve-fitting was incorrectly implemented with standard deviation rather than variance averaging (bug #12456).
A number of fixes for the LaTeX table generating sample script.
Fixes for the teeing and logging via the -l and -t command line arguments (bug #12489).
Fix for when XH bond vector data from a PDB file is missing for a spin system (bug #12487).
Many fixes for when structural data is missing.
The relax script is no longer overwritten if the log or tee file is not specified on the command line (bug #12498).
Missing RelaxError failure in the sequence handling code (found when trying to solve bug #12582).
A failure in the results.write() user function has been fixed (bug #12582).
Model selection no longer fails if no model is ever selected.
Model selection was failing if spins were deselected (bug #12591).
The directory name can now be part of the file name argument to results.read() (bug #12588).
Optimisation of only the diffusion tensor after calling fix() was failing if some spins were deselected (bug #12607).
The internal PDB reader was failing when the PDB file contained CONECT records (bug #12637).
