We are delighted to announce the publication of a new book, Computational and Visualization Techniques for Structural Bioinformatics Using Chimera, written by Forbes J. Burkowski (University of Waterloo).(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, 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).
A structure can be colored to show values of an attribute such as atomic B-factor. The image includes a molecular surface that has been clipped and capped, 2D labels, and a color key. Color Zone was used to color the planar cross-section of the surface (see image how-to).(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.
