Three way comparisons of F. hepatica juvenile contigs. The complete set of contigs generated by the Partigene pipeline was compared by tblastx with a set of ESTs or cDNA databases indicated in Additional file 2. The resulting tblastx scores were transformed in coordinates and represented in a triangular graph with Simitri. Each sequence is represented by a dot colour coded by its aggregated blast score and placed in the middle area if found in the three databases, on the corresponding cathetus if found in two databases. Sequences that match in only one of the databases or have no hits are not depicted, but their numbers are indicated. For clarity angle bisector lines were added. Comparisons are shown among (A) trematodes, cestodes, and turbellaria (B) cnidarians, mollusks, and annelids (C) flatworms (excluding F. hepatica), mollusks, and annelids (D) lophotrochozoans (excluding platyhelminths) ecdysozoans, and deuterostomes.
