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, funded by the National Institutes of Health (NIGMS P41-GM103311).
The default ribbon path is a smooth B-spline (transparent tan in the figure), which can diverge from the true positions of the backbone atoms (α-carbons shown as gray balls). A cardinal spline allows tracking the backbone more closely. Without smoothing (light blue), it follows the α-carbons exactly, or it can be combined with some “compromise” smoothing of strand and/or coil. Ribbon spline options can be set with the ribspline command or in the molecule model attributes.(More features...)
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.
