# AddRibbon

NAME

    AddRibbon - add ribbons (schematic drawing)

SYNOPSIS

    AddRibbon

DESCRIPTION

Create a schematic drawing with ribbons. The ribbons will go through the currently selected atoms, this will normally be all CA atoms in a protein.

If ribbons for helices and sheets are desired, certain properties of the residues must be set to give the necessary secondary structure information. The following properties are used:

        helix
        helix1, helix2,...
        sheet
        sheet1, sheet2,...
        strand1_1, strand1_2,...

These properties are set when a PDB file containing secondary structure information (HELIX and SHEET records) is read, or they can be calculated with the `CalcSecondary` command. They can also be set/modified using the `DefPropRes` command, a more convenient way for modifying the result of `CalcSecondary` is often to use the `WriteSecondary` command.

For sheets, the neighbour of the residues should be set with the `SetNeigh` command if the secondary structure was not read from a PDB file or calculated with `CalcSecondary`.

The created primitives will have exactly one of the following properties set:

        helix
        sheet
        coil

and for helix and sheet the numbered one from the residue (helix1,...) is also copied.

In addition, all created primitives have the property "ribbon".
