Japanese medaka HdrR vs Atlantic salmon LastZ results

Japanese medaka HdrR (Oryzias latipes, ASM223467v1) and Atlantic salmon (Salmo salar, Ssal_v3.1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 106. 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.
