P. J. Kraulisr* Atom and residue selection

| top | pdf |

A set of basic atom and residue selections are provided in MolScript for use as arguments to the graphics commands. Arbitrary subsets of atoms or residues can be specified by joining together the basic selections using a form of Boolean operators. Unfortunately, the Boolean expression feature may sometimes be difficult to understand for the non-expert user. One should consider the entire expression as a test to be applied to every atom or residue. Any atom or residue for which the Boolean expression evaluates to `true' will be selected as argument for the command.
