Web1 Jul 2015 · That is, by doing some complicated signal analysis and assigning a base quality score on Phred scale, or a Q-score, to every base observed. The Q-score is a value derived from the formula Q equals negative10 log P, where P is the probability that the base is wrongly called. A Q-score of 10 translates to 1 in a 10 chance of the base call being ...

WebThe sequences obtained were first analyzed using the Phred-Phrap-Consed programs. 27,28 The Phred program measures the quality of the data by attributing a score of 0–50 to each base of the chromatogram. Next, the Phrap program assembles a consensus sequence from the alignment of various overlapping sequences validated by Phred. WebThe bar below each nucleotide indicates that nucleotide’s Phred score. Bars at or above the line indicate Phred scores equal to or above 20 and are considered a high-quality read. “N”s indicate an undetermined nucleotide resulting from the overlap of two or more nucleotides at the same position.

WebThe y-axis on the graph shows the Phred quality scores, the x-axis shows the position in the read. So again you can see that the sequence reads in this file are 36 bases long. The average Phred score is depicted by the blue line, the median Phred score by the red line. The yellow boxes contain 50% of all Phred scores on a certain position.
