pepnet draws a helical net for an input protein sequence. This is a method of displaying the residues of a protein in a simple 3,4,3,4 repeating pattern that emulates at a simple level the arrangement of residues around an alpha helix. It is therefore easy to see patterns of amphipathicity that you may wish to investigate in more detail by using displays such as pepwheel. You can specify which residues to mark up in squares, diamonds and octagons.
