MDL´s Chemscape Chime is one of the first efforts to bring fast and interactive molecular graphics to the World Wide Web. Chime is a web-browser-plugin, unfortunately the current version 2.6 is only certified for Microsoft Internet-Explorer 5 and 6. Chime is based on Rasmol, one of the fastest and most widely used molecule viewers. Chime can be integrated into any web-page, and can be combined with JAVA-scripts and Rasmol-scripts giving the author the unique opportunity to create online tutorials, interactive viewing environments and similar stuff even on low-end-computers. For a complete coverage of what can be done with Chime, read the extensive tutorials and manuals provided at the Rasmol-homepage and at the Chime-site.

User Interface


An example-website made with Chime2. For more visit the MDL-homepage.

Chime has no user interface like a standalone program but consists of a display-window, which can be incorporated into a Web-page, and a popup-menu, the image is only a example of what can be done with chime. In addition there are many possibilities to add buttons (in a plain-HTML-text) and link them to scripts and so on for interactive manipulation of the displayed molecule. One can only view and manipulate the molecules integrated into the page by the author, it is not possible to load random-files on your own.


Feature-list taken from Chime-homepage

  • Displays structures directly within an HTML page, rather than through a helper application in a separate window.
  • Displays structures directly within an HTML table, to allow for multiple structures within an HTML page.
  • Supports MDL Molfile, MDL Rxnfile, Brookhaven Protein Databank (PDB), Minnesota Supercomputer Center's (MSC) XMol XYZ, Gaussian Input, IEMBL Nucleotide Format, RasMol Script File, Mopac Input File, and Chemical Structure Markup Language File.
  • Structures within the plug-in are "live"; they can be rotated within the plug-in in real time.
  • Displays 3D structures in any of the following formats: wireframe, backbone, sticks, spacefill, ball and stick, ribbons, strands, and cartoons. (3D rendering and RasMol Scripting code is based on Roger Sayle's popular RasMol rendering program.)
  • Supports multipart XYZ files, allowing HTML authors to animate molecular transformations.
  • Allows the HTML author to automatically rotate structures in Chime, with no user intervention.
  • Supports a Hot-link directly to MDL's ISIS/Draw 2.1 and above. Researchers choosea chemical structure displayed in an HTML page and automatically transfer that structure directly into ISIS/Draw via a Chime menu item.
