Hordeum vulgare GoldenPromise vs Triticum aestivum LastZ Results

Back to all analyses

Hordeum vulgare GoldenPromise (Hordeum vulgare subsp. vulgare, GPv1) and Triticum aestivum (Triticum aestivum, IWGSC) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release . Hordeum vulgare GoldenPromise 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: 3,208,694
