Chicken vs Zebrafish Translated Blat alignments

Chicken (Gallus gallus, Galgal4) and Zebrafish (Danio rerio, Zv9) were aligned using the Translated Blat alignment algorithm (Kent W, Genome Res., 2002;12(4):656-64) in Ensembl release 71. Chicken was used as the reference species. After running Translated Blat, the raw Translated Blat 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.
