EyeRibbons

DESCRIPTION

This Geometry module is an implementation of the Ribbons Algorithm by Mike Carson. It inputs a Chemistry Pyramid, calculates guide coordinates, and outputs protein ribbons as either threads or sheets. The Chemistry Pyramid should only contain the peptide backbone atoms (groups of N, C-alpha, C and O) in the correct order of appearance in the chain.
