Oryza meridionalis vs Oryza brachyantha LastZ Results

Back to all analyses

Oryza meridionalis (Oryza meridionalis, Oryza_meridionalis_v1.3) and Oryza brachyantha (Oryza brachyantha, Oryza_brachyantha.v1.4b) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 79. Oryza meridionalis 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.
