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

radial surface color

Radial Coloring

A surface can be colored radially, that is, by distance from a user-specified point. Additional options include coloring by distance from an axis or a plane. Different coloring schemes can be applied.

Neuraminidase Flowers

The image shows tetramers of influenza neuraminidase (Protein Data Bank entry 3k3a) styled as flowers. Three tetramers are colored pink, with a central metal ion in white and nearby residues in yellow, and a fourth tetramer is colored green to resemble leaves. Each monomer or “petal” is a six-bladed β-propeller. (More samples...)
