DESCRIPTION
"label" labels one or more atoms properties over a selection using
the python evaluator with a separate name space for each atom. The
symbols defined in the name space are:
name, resn, resi, chain, q, b, segi, type (ATOM,HETATM)
formal_charge, partial_charge, numeric_type, text_type
All strings in the expression must be explicitly quoted. This
operation typically takes several seconds per thousand atoms
altered.
To clear labels, simply omit the expression or set it to .
USAGE
label (selection),expression
EXAMPLES
label (chain A),chain label (n;ca),"%s-%s" % (resn,resi) label (resi 200),"%1.3f" % partial_charge
Users Comments
The following commnent,
label SELECTION, " %s" % ID
labels the SELECTION with atom ID numbers.
You can make more complicated selections/lables such as
label SELECTION, " %s:%s %s" % (resi, resn, name)
which will give you something like "GLU:139 CG"
