Fast, interactive display of molecular complexes containing millions of atoms is now possible, without plug-ins, on both desktop computers and smartphones. Our new molecular visualization tool, the NGL Viewer, enables easy visualization of even the largest structures for everyone in research and education. In addition, we have developed the new binary compressed Macromolecular Transmission Format (MMTF) to massively reduce network transfer and parsing times. With these advances, we are prepared for upcoming advances in experimental techniques that are already delivering structures of rapidly increasing size and complexity.
The NGL Viewer can be launched from the image display box on each structure summary page (e.g., 4HHB). For large structures comprising more than 10,000 residues in either the asymmetric unit or the biological assembly, the NGL Viewer is now the only supported tool (e.g., 4V99). For structures with a large asymmetric unit, a backbone-only structure is displayed by default to improve loading time. Display style and quality are optimized so that the viewer will run smoothly on both mobile and desktop systems, but can be customized for more powerful systems or for the generation of high resolution images.
For X-ray structures, crystallographic unit cells can be displayed, as well as “supercells” comprising a set of adjacent unit cells.
