Atta cephalotes vs Solenopsis invicta LastZ Results

Back to all analyses

Atta cephalotes (Atta cephalotes, Attacep1.0) and Solenopsis invicta (Solenopsis invicta, Si_gnG) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Metazoa release . Atta cephalotes 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: 650,370
