It addresses challenges in the size, scope, and disparate types of data attendant with cutting-edge experimental methods, while providing advanced options for high-quality rendering (interactive ambient occlusion, reliable molecular surface calculations, etc.) and professional approaches to software design and distribution. This article highlights some specific advances in the areas of visualization and usability, performance, and extensibility. ChimeraX is free for noncommercial use and is available from http://www.rbvi.ucsf.edu/chimerax/ for Windows, Mac, and Linux. | |||||||||

Image processing
-Atomic model buiding 1
Details | An initial hSERINC3 model was generated using AlphaFold v2.1 and the full database excluding PDB:6SP2. Low-confidence loops were removed from the model prior to fitting in the cryoEM map and side chains were retained. |
