Fusarium oxysporum vs Saccharomyces cerevisiae LastZ results

Fusarium oxysporum (Fusarium oxysporum f. sp. lycopersici, FO2) and Saccharomyces cerevisiae (Saccharomyces cerevisiae S288c, R64-1-1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Fungi release 110. Fusarium oxysporum 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.
