This WWW page enables you to draw an HCA plot using the program drawhca by Luc CANARD.

You have two ways for sending your data to the drawhca program through the Internet:

  • In the first case you need:
    - a WWW browser supporting upload file transfert;
    - an ASCII (text) file containing your sequence of amino-acids.
    Click here if you are in this case.

  • In the second case you must enter your sequence of amino-acids in a form (by typing it, or using a past from another window).
    Click here if you choose this case.
