Figure 6
Graphical representation of pairwise peak alignment. Pairwise alignment: E1 and E2 are experimental outputs. 49 solid lines (denoted by C1,...,C49) presents peak matching, which were aligned by both methods. 7 dashed lines and 8 dotted lines present matched peaks by the Naive method only and a peak alignment only, respectively. That is, there are 56 peak pairs by Naive and 57 by a peak alignment method and union of two peak alignment results are 64. After applying a cutoff value, 3 pairs (N5; N6; N7) and 2 pairs (M1; M2) were selected as correct matching by post-hoc. Final 54 peak pairs are denoted by P1,...,P54. 'x' presents 'failure to pass the cutoff 1.'
