Vitis vinifera vs Saccharum spontaneum LastZ Results

Back to all analyses

Vitis vinifera (Vitis vinifera, 12X) and Saccharum spontaneum (Saccharum spontaneum, Sspon.HiC_chr_asm) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release . Vitis vinifera 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: 594,172
