The RCSB was pleased to host the second workshop for the Collaborative Computational Project (CCP) for NMR on May 22, 2000 at NIST. The first workshop was held February 7-8, 2000 in Hinxton, UK. The CCP NMR (CCPN) project is funded by the Biotechnology and Biological Sciences Research Council (BBSRC) of the United Kingdom. The CCPN project aims to develop for the NMR community data exchange standards and software packages analogous to what the CCP4 project has developed for the crystallographic community. Further information about CCPN and workshop summaries are available at http://www.bio.cam.ac.uk/nmr/ccp/. The next CCPN meeting will be held in Florence, Italy in conjunction with the XIX International Conference on Magnetic Resonance in Biological Systems, August 20-25, 2000.
