WebA Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing. [1] [2] It was originally developed for the computer program Phred to help in the automation of DNA sequencing … WebQ Score Definition The sequencing quality score of a given base, Q, is defined by the following equation: Q = -10log10 (e) where e is the estimated probability of the base call being wrong. Higher Q scores indicate a smaller probability of error. Lower Q scores can result in a significant portion of the reads being unusable.
