Atom Selections

Conceptually, PyMOL atom selections are simply lists of atoms. These lists are used as input to many commands, as selection expression arguments

If you wish to use a selection expression more than once, then you can use the select command to associate it with a unique name that can be used repeatedly in other selection expressions.

An alphabetical list of selection operators is available along with a list of those that are deprecated.

Selection macros provide a quickhand way of specifying atoms without having to provide explicit operators.
