Presenting your structures: the CCP 4 mg molecular‐graphics software

CCP 4 mg is a molecular‐graphics program that is designed to give rapid access to both straightforward and complex static and dynamic representations of macromolecular structures. It has recently been updated with a new interface that provides more sophisticated atom‐selection options and a wizard to facilitate the generation of complex scenes. These scenes may contain a mixture of coordinate‐derived and abstract graphical objects, including text objects, arbitrary vectors, geometric objects and imported images, which can enhance a picture and eliminate the need for subsequent editing. Scene descriptions can be saved to file and transferred to other molecules. Here, the substantially enhanced version 2 of the program, with a new underlying GUI toolkit, is described. A built‐in rendering module produces publication‐quality images.
