Zea mays vs Setaria italica LastZ Results

Back to all analyses

Zea mays (Zea mays, B73_RefGen_v4) and Setaria italica (Setaria italica, Setaria_italica_v2.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release . Zea mays 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.


Number of alignment blocks: 367,182
