WebSNR is measured as the ratio of the peak height over the root-mean-square deviation (RMSD or standard deviation) value of the noise floor. Good SNR is typically > 10, especially for publication. A SNR of 3 (3σ) is minimally acceptable with a probability, also referred to as the confidence level, of the peak not being random noise at ~ 99.7%. WebIn addition, the peak height ratio, as measured by dividing the height of the lower quantity peak in relative fluorescence units by the height of the higher quantity allele peak, should …
