Human vs Gibbon LastZ alignments

Human (Homo sapiens, GRCh37) and Gibbon (Nomascus leucogenys, Nleu1.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 66. Human was used as the reference species. After running LastZ , the raw LastZ alignment blocks are chained according to their location in both genomes. During the final netting process, the best sub-chain is chosen in each region on the reference species.
