DESCRIPTION
"select" creates a named atom selection from a
selection-expression.
USAGE
select name, selection [, enable [, quiet [, merge [, state [, domain ]]]]]
ARGUMENTS
name = a unique name for the selection
selection = a selection-expression
NOTES
If a selection-expression with explicit surrounding parethenses is
provided as the first argument, then the default selection name
is used as the name argument.
EXAMPLES
select chA, chain A
select ( resn his )
select near142, resi 142 around 5
PYMOL API
cmd.select(string name, string selection)
