CARA is a program for assignment of NMR resonances in biomacromolecules and was developed in the group of Kurt Wüthrich at the Swiss Federal Institute of Technology ETH in Zurich, Switzerland. It continues to be developed and supported and can easily be installed on all major platforms
This is the front page of the CARA documentation Wiki. A Wiki is a platform for joint editing of HTML pages. We use the ZOPE version of a Wiki, called ZWiki. You'll find general Zwiki documentation at ZWiki:ZwikiDocs. The CARA Wiki has a HelpPage, RecentChanges, UserOptions and contents. This Site is running on ZOPE version 2.0.
The Wiki can only be changed by members of the Cara Definition Team. We welcome feedback and suggestions related to the Wiki and to Cara! Please send email regarding the wiki to the CDT. If you have a bug to report or feature you would like to see, please contact us. We are currently developing a CARA forum to facilate communication among users. If you have problems which cannot be solved using the wiki, contact us. We like to hear from users!

A new stable release 1.9.0 is available from the download site. This release adds functionality to the LUA commands to import spectra into projects and allows spectra which are not found during loading of the repository to be ignored. See News and release notes for details.
A beta release of CARA 1.9.1b18 includes support for larger spectra (64 bit) and a new scope for analysis of 4D spectra. It also supports relative pathnames for spectra.
NEW LUA script ChemShiftMapFromTwoPeakLists.lua to generate chemical shift mapping data from two peaklists.
NEW LUA script CompareProjects.lua to compare the assignments in two projects and report differences (assigned in only one, signficant shift deviations)
Updated LUA script WriteSparkyPeakList.lua so it can write 2D, 3D, and 4D sparky peaklists.
- NEWS Last update: September 18, 2015
Latest News on CARA and Cara wiki.
- Extension of CARA model and interface to handle isotope-labeling. This will support the analysis of multiple samples in projects which contain two or more chains with different isotope labeling schemes, site-specific labeling, or partially labeled residues (e.g. perdeuteration with back-protonation).
- LUA API tools for the extension of the menu interface to new functionality by user-programmable scripts.
- CALUA: CARA's scripting language
Documentation, Reference material and Supporting Scripts for CARA's built-in scripting language based on LUA
