Zebrafish vs Amazon molly LastZ results

Zebrafish (Danio rerio, GRCz11) and Amazon molly (Poecilia formosa, PoeFor_5.1.2) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 92. 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.
