Set SSBonds

Syntax:  set ssbonds backbone
         set ssbonds sidechain

The RasMol ssbonds parameter determines whether disulphide bridges are drawn between the sulphur atoms in the sidechain (the default) or between the alpha carbon atoms in the backbone of the cysteines residues. The actual display of disulphide bridges is controlled by the ssbonds command. Drawing disulphide bridges between alpha carbons is useful when the rest of the protein is shown in only a schematic representation such as backbone, ribbons or strands. his parameter is similar to the RasMol hbonds parameter.
