WebLab is not a plugin, but a stand-alone piece of software which is very nice for visualizing not only files in Molecular Simulation Inc.'s old *.msi format (before Accelerys bought MSI), but also in a variety of other formats such as *.pdb, *.xyz, etc. Very nice for display of a number of simple X-ray crystal structures.

A "Lite" version of this software is available for FREE from MSI for academic users. The PC-Windows version is very nice. The non-free professional version is very impressive, also. There is a Macintosh version that we have not tried here at NERMMW up to 12 July 1998. See the links below for information on this nice companion software to the commerical Cerius² software and related MSI products.
