Oryza glaberrima vs Oryza rufipogon LastZ results

Oryza glaberrima (Oryza glaberrima, Oryza_glaberrima_V1) and Oryza rufipogon (Oryza rufipogon, OR_W1943) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 76. Oryza glaberrima 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.
