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, nonprofit, 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.

Feature Highlight

Space Navigator demonstration

Space Navigator Input Device

Space Navigator is an inexpensive ($60) USB input device from 3Dconnexion for moving and rotating models in 3 dimensions. This animation (8 Mb) shows docking a phage enzyme (PDB 1v0e) into an electron microscopy map (EMDB 1333) using a space navigator and mouse. Works with Windows and Mac Chimera versions (details).

Gallery Sample


This image of a clathrin cage uses flat shading and edge highlighting. It is a copy of a PDB molecule of the month image made by Graham Johnson and Dave Goodsell. David Goodsell pioneered this visualization style. This image was made with the Multiscale tool, silhouette edging, and surface lighting turned off.

Protein Data Bank model 1xi4.
