Vitis vinifera vs Setaria italica LastZ results

Vitis vinifera (Vitis vinifera, 12X) and Setaria italica (Setaria italica, Setaria_italica_v2.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 93. Vitis vinifera 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.
