ASTRAL is a Java program for estimating a species tree given a set of unrooted gene trees. ASTRAL is statistically consistent under multi-species coalescent model (and thus is useful for handling ILS). It finds the that maximizes the number of induced quartet trees in the set of gene that are shared by the species tree. The algorithm has an exact version can run for small datasets (less than 18 taxa) and a more useful that can handle large datasets (103 taxa an 800 genes were analyzed in minutes).
