Nasonia vitripennis vs Atta cephalotes LastZ Results

Back to all analyses

Nasonia vitripennis (Nasonia vitripennis, Nvit_2.1) and Atta cephalotes (Atta cephalotes, Attacep1.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Metazoa release . Nasonia vitripennis 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: 78,046
