Dog vs Giant panda LastZ results

Dog (Canis lupus familiaris, ROS_Cfam_1.0) and Giant panda (Ailuropoda melanoleuca, ASM200744v2) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 105. Dog 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.
