for the amino acid sequence trees used to verify the assignment of paralog groups. We do not require that the amphioxus (Branchiostoma floridae) sequences are located within the group. Trees are computed with the Neighbor-Joining and Maximum Parsimony programs in the phylip package, both including and excluding the amphioxus data.
