Upcoming Events
UCSF ChimeraX (or simply ChimeraX) is the next-generation molecular visualization program from the Resource for Biocomputing, Visualization, and Informatics (RBVI), following UCSF Chimera. ChimeraX can be downloaded free of charge for academic, government, nonprofit, and personal use. Commercial users, please see ChimeraX commercial licensing.
ChimeraX is developed with support from National Institutes of Health R01-GM129325, Chan Zuckerberg Initiative grant EOSS4-0000000439, and the Office of Cyber Infrastructure and Computational Biology, National Institute of Allergy and Infectious Diseases.
Feature Highlight
3D images and time series from multichannel optical microscopy are shown in the Volume Viewer tool, with easy access to hiding/showing individual channels, changing their colors, and adjusting threshold levels with the mouse. The menu of style options includes “volume” (translucent blobs, as in the image), surface, mesh, maximum intensity projection, single plane, and orthoplanes. For convenience, the step size, region bounds, and display style of different channels of the same dataset are coupled, in that changing the setting of one channel automatically changes it for the others.
The image shows human induced pluripotent stem cells, with plasma membrane in violet red, EGFP-tagged fibrillarin (as a marker for nucleolus) in yellow, and DNA (nucleus) in turquoise. The data are publicly available from the Allen Cell Explorer website, dataset: AICS-14_0.
More features...Example Image
Atomic B-factor values are read from PDB and mmCIF input files and assigned as attributes that can be shown with coloring and used in atom specification. This example shows B-factor variation within a structure of the HIV-1 protease bound to an inhibitor (PDB 4hvp). For complete image setup, including positioning, color key, and label, see the command file bfactor.cxc.
Additional color key examples can be found in tutorials: Coloring by Electrostatic Potential, Coloring by Sequence Conservation
