==== Gene trees ====
The gene trees ideally are in [http://www.biomedcentral.com/1471-2105/10/356/ phyloXML] format, with taxonomy and sequence data in appropriate fields; but can also be in New Hamphshire (Newick) or Nexus format, as long as species information can be extracted from the gene names (e.g. "HUMAN" from "BCL2_HUMAN") ([http://forester.googlecode.com/files/gene_trees_rio.nh example]).
-All gene trees must be completely binary.
