• Converted the sequences of some alleles to their reverse complement sequences in the SeqSero2 database.
• Deleted some alleles from the SeqSero2 database because of the existence of mutations.
• Added a fliC 1,5,7 allele and a fliC 1,2,7 allele into the SeqSero2 database.
• Deleted the O54 allele.
• Fixed the bug that caused the misidentification of O9 and O2 by the micro-assembly workflow.
• Used Spades v3.15.5 to prevent the bug when running the micro-assembly workflow in Mac with M2 chip.
