Cattle vs Beluga whale LastZ results
Cattle (Bos taurus, ARS-UCD2.0) and Beluga whale (Delphinapterus leucas, ASM228892v3) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 114. Cattle 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.
