The Collaborative Computational Project for Electron cryo-Microscopy (CCP-EM, http://www.ccpem.ac.uk) supports users and developers in biological EM. The three principal aims are :
- Build a community for computational aspects of cryo-EM. Provide a focus for the cryo-EM community to interact with other projects and initiatives in structural biology.
- Support the users of software for cryo-EM through dissemination of information on available software, and directed training.
- Support for software developers including porting, testing, and distribution of software.
CCP-EM has developed a software suite , currently in beta testing, available from http://www.ccpem.ac.uk/download.php Web services are being developed which will be integrated into the West-Life environment.
