CCPN: The Collaborative Computing Project for NMR

CCPN was started by the UK BBSRC in 1999 to promote the integration, sharing, and collaborative development of NMR software. At the time NMR software was mostly stand-alone programs with limited facilities for data flow between them, and gathering project data for final deposition was a demanding task.

The CCP data model specifies how different programs can store all their data in a common repository, from sample preparation through NMR analysis to structure determination and validation. The data model is supported by subroutine libraries in Python, Java, and C with storage in XML files or databases. All code is generated from the data model, using CCPNs automatic code generation software.

Data exchange is further supported by the CcpNmr FormatConverter that lets you import and export data from more than thirty pre-existing data formats for NMR and structural biology. The CcpNmr ECI Deposition tool allows easy deposition of final data to the BioMagResBank and PDB.

CcpNmr Analysis is an interactive graphics program for NMR visualization and analysis, built on top of the CCP data model. It has a highly developed user interface with extensive support for assignment and data extraction. The user interface components originally developed for Analysis have been used to integrate a number of third-party programs, notably to produce the graphical user interface that is used for the Extend-NMR pipeline.
