Tetrahymena thermophila vs Phytophthora parasitica LastZ results

Tetrahymena thermophila (Tetrahymena thermophila, JCVI-TTA1-2.2) and Phytophthora parasitica (Phytophthora parasitica P1569, Phyt_para_P1569_V1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Protists release 111. Tetrahymena thermophila 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.
