Chime critically depends on the superb, beautiful, and amazingly fast rendering code, the extensive command language, and the near absence of bugs which Roger Sayle created and donated to the world as RasMol in 1992-1996. Here are the features of Protein Explorer, version 1.0, which make it easier to use, and more powerful, than RasMol. Can be used directly from the web, without installation. Can display any published molecule via web from the Protein Data Bank, without downloading a local copy. The 10 most recently loaded molecules can be reloaded from a menu which is remembered between sessions.
Initial view is maximally informative, showing number of chains, water, and hetero atoms.
See below for more about the initial view for NMR ensembles. Atom identifications, obtained by clicking with the mouse, are interpreted into a less abbreviated report. Preferences are remembered between sessions. Automatic slow rotation if desired. Rolling probe or true solvent accessible surfaces can be displayed and colored by distance from a reference structure, electrostatic potential or hydrophobicity.
