Human vs Dolphin BlastZ alignments

Human (Homo sapiens, GRCh37) and Dolphin (Tursiops truncatus, turTru1) were aligned using the BlastZ alignment algorithm (Schwartz S et al., Genome Res.;13(1):103-7, Kent WJ et al., Proc Natl Acad Sci U S A., 2003;100(20):11484-9) in Ensembl release 55. Human was used as the reference species. After running BlastZ , the raw BlastZ alignment blocks are chained according to their location in both genomes. During the final netting process, the best sub-chain is chosen in each region on the reference species.
