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.(Previous news...)
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.
Users can easily import structure-related data into Chimera in the form of attributes, or values associated with atoms, residues, or models. The data can be imported with Define Attribute and then represented visually with color ranges, atomic radii, or "worm" thickness. Such data can also be manipulated programmatically in Chimera, and in fact Chimera was designed with extensibility and programmability in mind. It is largely implemented in Python, with certain features coded in C++ for efficiency. Python is an easy-to-learn interpreted language with object-oriented features. All of Chimera's functionality is accessible through Python and users can implement their own algorithms and extensions without any Chimera code changes, so any such custom extensions will continue to work across Chimera releases. Many programming examples are provided to assist extension writers.(More features...)
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...)
