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 and the Office of Cyber Infrastructure and Computational Biology, National Institute of Allergy and Infectious Diseases.
Morphing between atomic structures can be calculated wih the morph command and played back in an animation. This movie shows morphing between two conformations of the FGFR1 kinase domain:
Morphing and other setup was done with the command file kmorph-prep.cxc, followed by interactively positioning the structure and saving the view with the command view name p1 (generally a session would also be saved at this point), then running kmorph-play.cxc to add 2D labels and record the movie.More features...
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.
