Software

We develop 4D-CHAINS, a software for fully automated protein backbone N-H and sidechain aliphatic C & H chemical shift assignment from 2 NMR spectra: a 4D TOCSY and a 4D NOESY. The program is free for non-commercial usage and can be downloaded from https://github.com/tevang/4D-CHAINS.

The main advantage of the method is the use of 4D spectra that offer higher resolution and allow NMR studies of larger structures compared to traditional 3D NMR approaches. 4D-CHAINS was successful in assigning automatically a protein composed of 248 amino acids. More information about the algorithm and its performance can be found in the following publication:
