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

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.

RNA Bases

Large ribosomal RNA is shown with individual bases depicted using solvent excluded molecular surfaces. Bases A, C, G, U are colored red, yellow, green, and blue. The surfaces were made with the Chimera multiscale tool in combination with the nucleic acid blobs plug-in. The image was raytraced using POVray.

Protein Data Bank model 1s72.
