The Collaborative Computing Project for NMR (CCPN) was started in 2000 to improve the interoperability of software for biomolecular Nuclear Magnetic Resonance (NMR), and to promote a collaborative community for software users and programmers. Over the past fifteen years, the project has produced the CcpNmr suite of software for interactive NMR data analysis and software integration, which is now used worldwide by >1000 users. Through its conferences and workshops, CCPN also promotes best practices in both computational and experimental aspects of NMR, thus helping to maximise the impact of biological NMR research. CCPN has a leading role in the development of a NMR data-exchange format and coordination of NMR instrumentation proposals for RCUK and BIS. With the current proposal we seek to continue the CCPN project and to further expand its user community. Hence, over the next grant period we aim to: 1. Maintain and expand the CCPN code base. 2. Expand the capabilities and versatility of the CCPN software package. 3. Facilitate NMR-based scientific developments in collaboration with the partners of the project and the NMR community at large. 4. Promote and expand user uptake and user development of the software. 5. Provide support for research data management (RDM). 6. Support the training of researchers, sharing of knowledge and exchange of best-practices by the UK and international NMR community.
