Dina workshop: Java biosequence alignment applet

This applet demonstrates algorithms for pairwise alignment described in the book Durbin et al: Biological Sequence Analysis, Cambridge University Press 1998, chapter 2.

Another page demonstrates construction and drawing of phylogenetic trees.

The alignment program

Type in two amino acid sequences (using the alphabet ARNDCQEGHILKMFPSTWYV) in the top-most two windows, then press the button.

E.g., try the example sequences HEAGAWGHEE and PAWHEAE:

Note that Microsoft Windows suffers from a limitation: a browser applet text component can contain only approx. 50,000 characters; all excess characters are discarded. This is not a limitation of this program, of Java, or of Netscape.
