CING

From NMR Wiki

CING stands for: "Common Interface for NMR structure Generation" and is known for structure and NMR data validation. Pronounced 'king'.

Project site: home page, video tutorials

CING was used to create NRG-CING. iCing is a web interface to CING. The same human interface can be exploited programmatically using something like this robot.

The following figures illustrate some of the capabilities offered by CING.

Generate Ramachandran plots

Identify secondary structure elements

Calculate a number of normality parameters and plot them vs. residue number

Limitations: CING in 2008 does not yet do much validation on sugars.

Running time: depends on number of residues mostly, typically takes from 2 minutes to 1 hour on the iCing server.

Requirements: python with matplotlib and many optional external programs such as Procheck.
