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

The relaxation dispersion model for the numeric solution (NS) to the Bloch-McConnell equations for SQ CPMG-type data using 3D magnetisation vectors. The model is labelled as NS CPMG 2-site 3D full in relax.

Parameters

The NS CPMG 2-site 3D full model has the parameters {R2A0, R2B0, ..., pA, Δω, kex}.

Code

The library code: https://sourceforge.net/p/nmr-relax/code/ci/master/tree/lib/dispersion/ns_cpmg_2site_3d.py

References

The function uses an explicit matrix that contains relaxation, exchange and chemical shift terms. It does the 180deg pulses in the CPMG train. The approach of Bloch-McConnell can be found in chapter 3.1 of Palmer, A. G. Chem Rev 2004, 104, 3623-3640. This function was written, initially in MATLAB, in 2010.
