CCP4mg is a molecular-graphics program designed for rapid access to both straightforward and complex static and dynamic representations of macromolecular structures. The program has been updated with a new interface that offers more sophisticated atom-selection options and a wizard to facilitate the creation of complex scenes. These scenes can include a mix of coordinate-derived and abstract graphical objects, such as text, vectors, geometric objects, and imported images, enhancing the visual representation and eliminating the need for subsequent editing. Scene descriptions can be saved and transferred to other molecules. The enhanced version 2 of CCP4mg features a built-in rendering module that produces publication-quality images, and it is free software under the LGPL license. The program includes tools for creating complex scenes and movies, automatic generation of multiple drawing styles, highlighting of equivalent structural features, and the prediction and visualization of quaternary structure and molecular interfaces. It also supports electron density mapping, text annotations, overlays, and the addition of arbitrary geometric primitives. CCP4mg offers analysis tools for molecular surfaces, structural and sequence alignments, and the Protein Interfaces, Surfaces and Assemblies (PISA) service for exploring interfaces and predicting quaternary structures. The program can output high-definition images and create movies with various frame rates and qualities. Future developments include enhancements to the sequence viewer, normal-mode visualization, and polysaccharide cartoons.CCP4mg is a molecular-graphics program designed for rapid access to both straightforward and complex static and dynamic representations of macromolecular structures.
