Data needed for perfect phylogeny

[Richa Agarwala]

	I am writing a program which finds out whether the input
	data has a perfect phylogeny or not. Roughly speaking, by
	perfect phylogeny I mean that the tree should have the property
	that nodes having the same character state induce a subtree.

	I would like to know how I can get some 'real world' data
	for my program.

	Thanks,
	Richa
