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.
Special representations of DNA and RNA can be displayed with the Nucleotides tool or the command nucleotides. Different levels of abstraction are available. The figure shows a ribbon backbone combined with the following sidechain (sugar/base) options:
BILD format was used in Chimera to annotate the barrel structure of green fluorescent protein with its centroid, major axis (red arrow), and an enclosing cylinder (shown with green hoops). The BILD file green.bild was generated with the python program green.py using the coordinates in green.pdb. Gallery entry courtesy of Mike Ess, Yeast Resource Center, University of Washington.
