Trypanosoma brucei vs Pythium arrhenomanes LastZ results

Trypanosoma brucei (Trypanosoma brucei, TryBru_Apr2005_chr11) and Pythium arrhenomanes (Pythium arrhenomanes ATCC 12531, par_scaffolds_v1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Protists release 111. Trypanosoma brucei 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.
