RasMol is a molecular graphics program intended for the visualisation of proteins, nucleic acids and small molecules. The program is aimed at display, teaching and generation of publication quality images.

The program reads in a molecule coordinate file and interactively displays the molecule on the screen in a variety of colour schemes and molecule representations. Currently available representations include depth-cued wireframes, ‘Dreiding’ sticks, spacefilling (CPK) spheres, ball and stick, solid and strand biomolecular ribbons, atom labels and dot surfaces.

Supported input file formats include Protein Data Bank (PDB), Tripos Associates’ Alchemy and Sybyl Mol2 formats, Molecular Design Limited’s (MDL) Mol file format, Minnesota Supercomputer Center’s (MSC) XYZ (XMol) format, CHARMm format, CIF format and mmCIF format files.
