Hyaloperonospora arabidopsidis vs Pythium aphanidermatum LastZ results

Hyaloperonospora arabidopsidis (Hyaloperonospora arabidopsidis, HyaAraEmoy2_2.0) and Pythium aphanidermatum (Pythium aphanidermatum DAOM BR444, pag1_scaffolds_v1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Protists release 111. Hyaloperonospora arabidopsidis 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.
