The effect of M-value threshold on sensitivity and specificity for detection of different degrees of probe-target mismatch: (A) ≥ 1 mismatch (B) ≥ 2 mismatches (C) ≥ 3 mismatches and (D) ≥ 4 mismatches. M-values ranging from -3.0 to -0.25 are plotted with an interval of -0.25. An M-value of <-0.75 was chosen for classifying a probe as divergent compared to the sequence of reference strain NCTC 11168.
