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.

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

Description

This major feature 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. As this is a highly invasive change, touching almost all of the relax analysis types and modifying the GUI, the minor version number has been incremented and all of the 2.0.x version numbering has been skipped. ..→
