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 Trott and Palmer 2002 2-site off-resonance relaxation dispersion model for R1rho-type data for all time scales with pA ≫ pB. This model is labelled as TP02 in relax. Parameters The TP02 model has the parameters {R1ρ', ..., pA, Δω, kex}. Reference The reference for the TP02 model is: Trott, O. and Palmer, 3rd, A. G. (2002). R1rho relaxation outside of the fast-exchange limit. J. Magn. Reson., 154(1), 157-160. (DOI: 10.1006/jmre.2001.2466) Related models The MP05 model improves on this model. Links The implementation of the TP02 model in relax can be seen in the: relax manual, API documentation, ..→
