Release Notes: This is a major feature and bugfix release that marks the completion of the N-state model analysis implementation. The N-state model allows single structures or ensembles of static structures to be analyzed and compared using residual dipolar couplings (RDCs), pseudo-contact shifts (PCSs), and distance restraints via NOEs. In addition to alignment tensors, the populations or probabilities of each state can be optimized, as well as the position of the paramagnetic center when PCSs are used.
Release Notes: This is the Python super-compatibility release; relax will now run on Python 2.3 all the way to Python 3.3, a span of over 9 years of Python development. Some exceptions are Python 3.0 (as numpy and scipy are not compatible with that release), the execution of external programs in Python 2.3 not being supported, and the GUI currently not available on Python 3 due to the wxPython project not being compatible with this new Python design yet. A number of important bugfixes are also included.
Release Notes: This release introduces the new concept of a container for data linking two atoms or spins, the interatomic data design. This is for NMR data such as the magnetic dipole-dipole interaction between two spins (including relaxation and RDC data) and NOESY data. This design significantly extends relax's flexibility and opens up new analysis type possibilities. Additional features and changes include the update of the relax copyright license to GPLv3, support for absolute or signless RDCs, and elimination of many GUI bugs in MS Windows.
Release Notes: Features include a complete restructuring of the user functions with automatically generated front ends in all UIs, allowing all to be accessible from the GUI. The core of the specific analysis API has been redesigned to simplify adding new analysis types. The XML formatted save files have been redesigned for both numerical accuracy and readability. Data pipes can now be grouped into data bundles, and GUI analysis tabs are now associated with a specific bundle. BMRB export/import and support for Bruker Dynamics Centre relaxation data files are now tightly integrated into the GUI.
Release Notes: The relax manual has been significantly updated by completion of the model-free analysis chapter, the addition of GUI screenshots and descriptions, a description of Gary Thompson's multi-processor framework, and general updates and improvements. For those who install relax using the scons "install" target, the *.pyc and *.pyo files are now properly created for faster startup. The Bruker Protein Dynamics Centre user function "pdc" has been renamed "bruker". The Bruker and BMRB user functions have been added to the menu system. A test suite bug triggered via Fink has been eliminated.
Release Notes: This release focuses on more complete Mac OS X support and the prettifying all of the user interfaces (UIs). The new features include full Mac OS X support via fink and the Mac application DMG file (for Leopard, Snow Leopard and Lion with PPC, i386, and x86_64 CPUs), colored terminal output in the prompt/script UI modes, the ability to run the full relax test suite within the GUI mode, general improvements throughout the GUI, support for wxPython 2.9, faster program startup, improved formatting of the HTML version of the user manual, and expansion of the multi-processor framework.
Release Notes: This is the second version of the relax GUI, and is a major code rewrite. It now functional on GNU/Linux, Mac OS X, and MS Windows. In addition to many bugfixes, there are improvements to the frame order theory, N-state model analysis, handling of RDC and PCS values, a number of new user functions for structure creation, displacement, and superimposition and for model-free result visualisation in PyMOL, and a redesign of the auto-analyses to have all input data pre-loaded into a relax data pipe for support of non-protein organic molecules in the dauvergne_protocol auto-analysis.
Release Notes: This is a major feature release. It adds the ability to run relax on clusters or grids of computers via the MPI protocol. This merges in Gary Thompson's multi-processor branch, which was started all the way back in 2007. The "multi" package introduces two processor fabrics, the standard uni-processor mode and the mpi4py mode for using the MPI protocol with Python. The model-free analysis code has been parallelized to take advantage of the multi-processor modes, significantly speeding up calculations on clusters with near perfect scaling efficiency.
Release Notes: This is a major feature release, and all users are recommend to upgrade. The major features include the integration of relax and the BMRB via the reading and writing of the BMRB NMR-STAR format files for model-free analyses, support for reading the XYZ 3D structure files used in organic chemistry, significant GUI improvements, and better support for the Bruker Protein Dynamics Centre (PDC) files. In addition a large number of bugs have been resolved. All together, this is a large release consisting of just under 2000 individual changes.
