Mouse vs Zebrafish Translated Blat alignments

Mouse (Mus musculus, GRCm38) 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 68. Mouse 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.
