Oryza barthii vs Oryza glaberrima LastZ results

Oryza barthii (Oryza barthii, O.barthii_v1) and Oryza glaberrima (Oryza glaberrima, Oryza_glaberrima_V1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 75. Oryza barthii 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.
