What's new?

News & Updates Version 5 of relax. The latest relax release now supports the new versions of wxPython (Phoenix), giving relax a more modern GUI. Migration to SourceForge After the Gna! shutdown at the start of 2017, relax has finally in 2019 been fully migrated to the SourceForge infrastructure. Gna! is permanently shut down! A migration to another open source infrastructure is planned. This will include web hosting for http://www.nmr-relax.com, source code repositories, bug and other trackers, new reports, download pages, and possible a svn to git conversion. Tutorial added Tutorial for sorting data stored as numpy to on-resonance R1rho analysis Version 4 of relax With the latest relax release merging in years of developments in the frame order analysis, the major number has been incremented to relax 4. Tutorial added Tutorial for manual regarding the relaxation dispersion auto-analysis in the GUI Tutorial added Tutorial for R1/R2 Relaxation curve-fitting analysis on varian recorded as fid interleaved Matplotlib example added Matplotlib example Tutorial added Relaxation dispersion analysis R1_rho recorded on varian Tutorial added Relaxation dispersion analysis cpmg fixed time recorded on varian as fid interleaved Tutorial added Adding relaxation dispersion models to relax wiki namespace changed The wiki is now placed at: http://wiki.nmr-relax.com as of 19 of July 2013 GPL License The License has been changed to GPL v3.

Did you know... %PAGE% The Baldwin 2014 2-site exact solution relaxation dispersion model for SQ CPMG-type data for all time scales whereby the simplification R2A0 = R2B0 is assumed. This model is labelled as B14 in relax. The advantage of this code will be that you'll always get the right answer provided you've got 2-site exchange, in-phase magnetisation and on-resonance pulses. Comments from the Author During the implementation of model B14, Andrew Baldwin wished to raise the attention to: 1) Danger of errors of approximations. 2) That optimal accuracy analysis should include off resonance effects.
