Thank you, Angel. That's certainly what it is. Angel Herraez wrote:

For proteins, control points are chosen to be the center of the peptide bond, and the ribbon is drawn in the direction of the carbonyl oxygen (thus roughly defining the peptide planes). For nucleic acids, the control points are the midpoints between adjacent backbone phosphorus atoms, and the ribbon is drawn in the direction of the C6 carbon. A hermite curve is used. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
