relax is a program designed for the study of molecular dynamics of organic molecules, proteins, RNA, DNA, sugars, and other biomolecules through the analysis of experimental NMR data.

It supports exponential curve fitting for the calculation of the R1 and R2 relaxation rates, calculation of the NOE, reduced spectral density mapping, the Lipari and Szabo model-free analysis, study of domain motions via the N-state model or ensemble analysis and frame order dynamics theories using anisotropic NMR parameters such as RDCs and PCSs, the investigation of stereochemistry in dynamic ensembles, and the analysis of relaxation dispersion.


The relax documentation page is http://www.nmr-relax.com/docs.html.

The relax user manual can be browsed online at http://www.nmr-relax.com/manual/index.html, or viewed in PDF form at http://download.gna.org/relax/manual/relax.pdf.
