Lucilia cuprina vs Glossina austeni LastZ results

Lucilia cuprina (Lucilia cuprina, ASM118794v1) and Glossina austeni (Glossina austeni, GausT1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Metazoa release 99. Lucilia cuprina 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.
