                                  pepnet 



Function

   Displays proteins as a helical net

Description

   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.

Usage

   Here is a sample session with pepnet


% pepnet -sask 
Displays proteins as a helical net
Input protein sequence: tsw:gcn4_yeast
     Begin at position [start]: 253
       End at position [end]: 274
Graph type [x11]: cps

Command line arguments

   Standard (Mandatory) qualifiers:
  [-sequence]          sequence   Protein sequence filename and optional
                                  format, or reference (input USA)
   -graph              graph      [$EMBOSS_GRAPHICS value, or x11] Graph type
                                  (ps, hpgl, hp7470, hp7580, meta, cps, x11,
                                  tekt, tek, none, data, xterm, png)

   Additional (Optional) qualifiers (* if not always prompted):
*  -squares            string     [ILVM] By default the aliphatic residues
                                  ILVM are marked with squares. (Any string is
                                  accepted)
*  -diamonds           string     [DENQST] By default the residues DENQST are
