If you're a bio-scientist or researcher, then this program provides an excellent platform upon which to graphically represent molecular structures. Bioclipse provides functionality for chemo and bioinformatics but can also be extended via plugins to provide added functionality for many more areas.
Firstly, you'll need to make sure that you've got at least Java 1.5 or newer installed as this is an open source java based platform. Once opened, you are presented with the Bioclipse Workbench view which displays molecules in 3D. Next to this you have the editor window where you can work with editing files and perform saves, copy and pastes etc. finally you have the perspective window which is a collection of views and editors such as the Chemoinformatics view which displays information related to chemoinformatics like 2D-editing, 3D-visualization etc.
For anyone involved in molecular science, this is a simple but powerful program that will make your graphical presentations look much more professional.
