I have had a go at generating a tutorial page for the DP part of Biojava:- http://gadfly.gen.cam.ac.uk/~davidh/dp-doc.html Before I invest any more time on writing more pages on this, I thought I'd get some comments. Is this too much like a code walkthrough that someone could have done readily for themselves anyway just by reading the source of the Dice.java example? Regards, David Huen
