News

December 2, 2016

Chimera production release 1.11.2 is now available. This version has been updated to work with changes in NCBI Blast and to avoid crashes on Mac Sierra (see the release notes for details).

September 24, 2016

Production release candidate (version 1.11.2) is available, superseding 1.11.1. The new version has been updated to work with changes in NCBI Blast (see release notes). Please try it and report any problems.

August 27, 2016

A production release candidate (version 1.11.1) is now available. Please try it and report any problems. See the release notes for what's been fixed since 1.11. The 1.11 release series will be the last to support 32-bit builds.

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

realignment dialog

Multiple Sequence Alignment

Multiple sequence alignment of structure chains in Chimera or realignment of the sequences in an existing alignment can be performed using web services hosted by the UCSF RBVI. The following programs are provided:

The result is automatically shown in Multalign Viewer. (Sequences can also be added to an alignment one by one without a web service, but true multiple sequence alignment is often advantageous.) (More features...)

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...)
