Oryza sativa Japonica Group vs Oryza glaberrima LastZ Results

Back to all analyses

Oryza sativa Japonica Group (Oryza sativa Japonica Group, IRGSP-1.0) and Oryza glaberrima (Oryza glaberrima, Oryza_glaberrima_V1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 76. Oryza sativa Japonica Group 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: 183,406
