Mouse vs Chinese hamster PICR LastZ results

Mouse (Mus musculus, GRCm39) and Chinese hamster PICR (Cricetulus griseus, CriGri-PICRH-1.0) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 115. Mouse 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.
