Pig vs Pig - Hampshire LastZ results

Pig (Sus scrofa, Sscrofa11.1) and Pig - Hampshire (Sus scrofa, Hampshire_pig_v1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 98. Pig 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.
