Chicken vs Common wall lizard LastZ results

Chicken (Gallus gallus, bGalGal1.mat.broiler.GRCg7b) and Common wall lizard (Podarcis muralis, PodMur_1.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 107. Chicken was used as the reference species. After running LastZ, the raw LastZ alignment blocks were chained according to their location in both genomes. During the final netting process, the best sub-chain was chosen in each region on the reference species.
