Upcoming Ensembl Platform Transition

This is the final release of its kind on this website.

In summer 2026, this site will bring you to the new Ensembl platform currently at beta.ensembl.org.

Pig vs Pig - Berkshire LastZ results

Pig (Sus scrofa, Sscrofa11.1) and Pig - Berkshire (Sus scrofa, Berkshire_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.
