Upcoming Events

UCSF Chimera is a highly extensible program for interactive visualization and analysis of molecular structures and related data, including density maps, supramolecular assemblies, sequence alignments, docking results, trajectories, and conformational ensembles. High-quality images and animations can be generated. Chimera includes complete documentation and several tutorials, and can be downloaded free of charge for academic, government, non-profit, and personal use. Chimera is developed by the Resource for Biocomputing, Visualization, and Informatics (RBVI), funded by the National Institutes of Health (NIGMS P41-GM103311).

UCSF ChimeraX (or simply ChimeraX) is the next-generation molecular visualization program from the RBVI, following UCSF Chimera. It is in early development and not yet publicly released, with release anticipated sometime in 2016.

Feature Highlight

density display

Density Display

Electron density maps can be read from local files or fetched from databases. Chimera's Volume Viewer allows adjusting contour levels interactively, showing multiple isosurfaces for a given map, and restricting display to a zone around selected atoms. The figure shows PDB entry 2fma and its electron density map. Settings are similar to those described in the Density Display tutorial. See also: Chimera volume display guide

Gallery Sample

Orexin Receptor Complex

The image shows the structure of the human OX2 orexin receptor bound to the insomnia drug suvorexant, Protein Data Bank entry 4s0v. The drug is shown as spheres colored by element, and the receptor as ribbons with secondary structure elements rainbow-colored from blue at the N-terminus to red at the C-terminus. (More samples...)
