News & Updates 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% Intro This tutorial is based on the analysis of NMR data from the paper: The inverted chevron plot measured by NMR relaxation reveals a native-like unfolding intermediate in acyl-CoA binding protein. Kaare Teilum, Flemming M Poulsen, Mikael Akke. Proceedings of the National Academy of Sciences of the United States of America (2006). http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1458987 The data is recorded as FID interleaved. Preparation You want to make a working dir, with different folders peak_lists spectrometer_data scripts You can create the folders by mkdir peak_lists spectrometer_data scripts In the folder spectrometer_data should be the files: fid and procpar as the output from recording fid ..→
