Bombus terrestris vs Apis mellifera (DH4) LastZ results

Bombus terrestris (Bombus terrestris, Bter_1.0) and Apis mellifera (DH4) (Apis mellifera, Amel_HAv3.1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Metazoa release 102. Bombus terrestris 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.
