Ribbon Ribbon icon

Ribbon creates and displays VRML ribbon representations of proteins. It can be used on nucleic acids, but chain ends may not be handled well.

**Note that the command resrepr provides a (non-VRML) ribbon representation that better shows the secondary structure of proteins. Other advantages of resrepr are greater control over ribbon color and better performance with nucleic acid structures.

Ribbon is an extension in the Utilities category. There are several ways to start an extension.

Starting Ribbon opens a dialog box asking which model to base the ribbon upon, and offering a variety of ribbon types:

Once Okay in the dialog box is clicked, a VRML ribbon will be opened as the lowest available model number. If the only structure open is a protein in model 0, for example, for example, the ribbon will be opened in model 1. The ribbon object can be displayed/undisplayed (with the command objdisplay) or closed independently of the protein it represents (with the Model Panel or the command close).
