 The CCPN system works alongside the Bio Mag Res Bank which continues to handle archiving NMR database depositions; the CCPN standard is for active data exchange and in-program manipulation.Although NMR spectroscopy remains at the core of the data standard it naturally expands into other related areas of science that support and complement NMR.These include molecular and macromolecular description, three-dimensional biological structures, sample preparation, workflow management and software setup.
