5 About CCP4 CCP4 stands for “Collaborative Computational Project Number 4” One of several CCPs set up in the UK to advance and support scientific software development CCP4 was set up in the late 1970’s to bring together the leading developers of software in the field of protein X-ray crystallography in the UK The aim was to assemble a comprehensive collection of software to satisfy the computational requirements of the relevant UK groups
