Japanese medaka HdrR vs Midas cichlid LastZ results

Japanese medaka HdrR (Oryzias latipes, ASM223467v1) and Midas cichlid (Amphilophus citrinellus, Midas_v5) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 94. Japanese medaka HdrR 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.
