Collaborative Computational Project Number 4
The Collaborative Computational Project Number 4 in protein crystallography or (CCP4) was set up in 1979 in the United Kingdom to support collaboration between researchers software development and assemble a comprehensive collection of software for structural biology.
CCP4 was originally supported by the UK Science and Engineering Research Council (SERC), and is now supported by the Biotechnology and Biological Sciences Research Council (BBSRC). The project is coordinated at CCLRC Daresbury Laboratory. The results of this effort gave rise to the CCP4 program suite, which is now distributed to academic and commercial users world-wide.
