Atta cephalotes (Leaf-cutter ant) vs Apis mellifera (Honey bee, DH4) LastZ results

Atta cephalotes (Leaf-cutter ant) (Atta cephalotes, Attacep1.0) and Apis mellifera (Honey bee, DH4) (Apis mellifera, Amel_HAv3.1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Metazoa release 102. Atta cephalotes (Leaf-cutter ant) 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.
