Relationship of reference sequence quality scores of putative SNPs and variant frequency ( VF ). High correlation between reference sequence quality scores of putative SNPs and VF was observed in the data set of all putative SNPs (A). When putative SNPs with a Sanger quality score of less than 35 were removed, the correlation disappeared, showing that SNPs with high VF are false-positive SNPs due to sequencing errors in BES Sanger sequences (B).
