Arabidopsis thaliana vs Ostreococcus lucimarinus LastZ results

Arabidopsis thaliana (Arabidopsis thaliana, TAIR10) and Ostreococcus lucimarinus (Ostreococcus lucimarinus CCE9901, ASM9206v1) 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.
