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 [1]:

• 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 [2], 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.
