Syntax: set hbonds backbone
set hbonds sidechain
The RasMol hbonds parameter determines whether hydrogen bonds are drawn between the donor and acceptor atoms of the hydrogen bond, set hbonds sidechain or between the alpha carbon atoms of the protein backbone and between the phosphorous atoms of the nucleic acid backbone, set hbonds backbone. The actual display of hydrogen bonds is controlled by the hbonds command. Drawing hydrogen bonds between protein alpha carbons or nucleic acid phosphorous atoms is useful when the rest of the molecule is shown in only a schematic representation such as backbone, ribbons or strands. his parameter is similar to the RasMol ssbonds parameter.
