Anopheles gambiae vs Anopheles dirus LastZ results

Anopheles gambiae (Anopheles gambiae, AgamP4) and Anopheles dirus (Anopheles dirus, AdirW1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Metazoa release 99. Anopheles gambiae 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.
