This is a Javascript version of a molecular browser for XML/CML files. It runs on "any XML-aware browser" which at present is MSIE5 or 6. It dynamically converts cml2svg and for this reason also requires an SVG plugin such as Adobe's.

It is destined as an open-source tool for displaying and managing molecular information especially for individual scientists or those collaborating in open programs. Future developments may include data and molecule entry.

The components of the system are:

• The XML-CML engine in Javascript (display.js and individual *.html files)
• A large number of molecules in CML. These have been converted from other formats and this process is not yet validated. There will be many different styles of molecule and JUMBO3 is intended to make the best educated guess as to how to present the information.

The browser is only for display at present, but interactivity will come later. The main screen has four components:

• TopLeft: controls to alter the display (scale, etc.). Mouseover describes each one
• Left: List of molecules. Many have no title other than a reference number. Each molecule is in a separate *.xml file.
• Main display. The molecule is drawn here. 2D molecules (connection tables) are draw if there are coordinates. At present the automatic layout facility is not implemented in Javascript and is run offline. 3D molecules are draw as one of 3 projections (x, y, z). They can be rotated (NOT interactively) by typing a rotation angle into "3D" box. Note that 3D molecules have NO depth-related presentation at the moment and atoms will always overlay bonds. Chirality (wedge/hatch) is extremely misleading and is dubious in "3d" coordinates. The test molecules may not always display. Crystallography is not yet implemented.
• Bottom: annotations. JUMBO3 will pick up titles and comments in XML files.

Use with care. Not all errors have been trapped (i.e. don't try scales of zero!). Have fun.
