Welcome to CARA

This is the official website of CARA (Computer Aided Resonance Assignment). CARA is a software application for the analysis of NMR spectra and computer aided resonance assignment which is particularly suited for biomacromolecules. Dedicated tools for backbone assignment, side chain assignment, and peak integration support the entire process of structure determination. CARA was developed in Professor Kurt W├╝thrich's group. Continuing development and support is provided by a group of volunteers.

CARA is free software (see licence terms). Precompiled native executables are provided on all major platforms for easy installation and operation.


CARA can be downloaded from the CARA Downloads page.


CARA documentation is available from the CARA Documentation page.
