Pig vs Pig USMARC LastZ results

Pig (Sus scrofa, Sscrofa11.1) and Pig USMARC (Sus scrofa, USMARCv1.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 97. 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.
