Zebrafish vs Siamese fighting fish LastZ results

Zebrafish (Danio rerio, GRCz11) and Siamese fighting fish (Betta splendens, fBetSpl5.2) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 98. Zebrafish was used as the reference species. After running LastZ, the raw LastZ alignment blocks were chained according to their location in both genomes. During the final netting process, the best sub-chain was chosen in each region on the reference species.
