News

November 17, 2018

Chimera production release 1.13.1 is now available; see the release notes for what's new. The Mac version requires OS 10.10 or later.

October 22, 2018

Mac users: the 1.13.1 release candidate and recent daily builds contain a fix for Mojave (OS 10.14). These versions require OS 10.10 or later.

September 21, 2018

Mac users are advised to hold off upgrading to Mojave until we find a fix for Chimera buttons not being shown until the windows containing them are resized.

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), supported in part by the National Institutes of Health (P41-GM103311).

UCSF ChimeraX (or simply ChimeraX) is the next-generation molecular visualization program from the RBVI, following UCSF Chimera.

Feature Highlight

phosphomannomutase morphing animation

Morphing

Different conformations and even different proteins can be compared by morphing from one structure to another. Users can specify the method of coordinate interpolation and how many intermediate structures should be generated. The result is displayed in Chimera's trajectory viewer, MD Movie. The morph can then be saved in coordinate form or recorded as an animation. See also: Animation Gallery

Gallery Sample

Peroxiredoxin Wreath

Peroxiredoxins are enzymes that help cells cope with stressors such as high levels of reactive oxygen species. The image shows a decameric peroxiredoxin from human red blood cells (Protein Data Bank entry 1qmv), styled as a holiday wreath.
