Zebrafish vs Turquoise killifish LastZ results

Zebrafish (Danio rerio, GRCz11) and Turquoise killifish (Nothobranchius furzeri, Nfu_20140520) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 101. 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.
