Compared to Chimera, ChimeraX brings together:
(A) significant performance and graphics enhancements
- interactive display of very large atomic structures and maps
- interactive ambient-occlusion lighting and/or directional shadows
- fast and robust molecular surfaces
- fast mmCIF reader
(B) new implementations of Chimera’s most highly used tools
- map fitting, segmentation, volume eraser, volume filtering
- morph maps or atomic structures
- play back volume series or atomic trajectories
- view ligand-receptor docking results
- find H-bonds, find contacts and clashes
- virtual mutation, amino acid sidechain rotamers
- radial coloring, coloring by map value
- coloring by molecular lipophilicity potential, B-factor, etc.
- animatable 2D labels and arrows
- shape command to draw spheres, cylinders, etc.
- sequence viewer with sequence-structure crosstalk
- interface to Modeller comparative modeling
(C) entirely new features
- tube (curved cylinder) helices in cartoons
- chain-chain contact diagram
- H-bond or crosslink length histogram
- built-in HTML browser with mechanism for click-to-execute commands
(D) support for new areas
- virtual reality
- light-sheet microscopy
- medical imaging data
(E) major ease-of-use advances
- toolbar with icons to perform actions with a single click
- basic "undo"
- more logical commands and more powerful command-line specification
(F) a web repository (ChimeraX Toolshed) for developers to contribute plugins
