relax - Molecular dynamics by NMR data analysis

Analysis software for: Model-free, NMR relaxation (R1, R2, NOE), reduced spectral density mapping, relaxation dispersion, N-state models, frame order theory.

Relaxation dispersion analysis

Since the release of relax version 3.1.0, relax supports the analysis of NMR relaxation dispersion data (see Morin et al., 2014). All dispersion data types are supported as well as an almost complete list of relaxation dispersion models, both analytic and numeric.

Data types

The following relaxation dispersion data types are supported by relax:

Models

Numerous analytic and numeric relaxation dispersion models are supported by relax. It the model you are interested is not yet supported, please see the tutorial for adding dispersion models to relax.

Experiment independent models

The following models are independent of the experiment type:
