Stickleback vs Cod LastZ alignments

Stickleback (Gasterosteus aculeatus, BROADS1) and Cod (Gadus morhua, gadMor1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 64. Stickleback was used as the reference species. After running LastZ , the raw LastZ 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.
