Arabidopsis thaliana vs Trifolium pratense LastZ results

Arabidopsis thaliana (Arabidopsis thaliana, TAIR10) and Trifolium pratense (Trifolium pratense, Trpr) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 94. Arabidopsis thaliana 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.
