Oryza sativa Indica Group vs Oryza brachyantha LastZ results

Oryza sativa Indica Group (Oryza sativa Indica Group, ASM465v1) and Oryza brachyantha (Oryza brachyantha, Oryza_brachyantha.v1.4b) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 67. Oryza sativa Indica Group 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.
