RasMol is a molecular viewer program used for visualizing proteins, nucleic acids and small molecules. The program displays molecules and teaches about bonding by reading in molecular co-ordinate files and interactively displays the molecule on the screen in a variety of representations and colour schemes. It is launched in Model ChemLab from the Chemical Properties Dialog Box .
RasMol was developed at the University of Edinburgh's Biocomputing Research Unit and the BioMolecular Structure Department, Glaxo Research and Development, Greenford, U.K.
