An efficient post-hoc integration method improving peak alignment of metabolomics data from GCxGC/TOF-MS

Table 3 The number of aligned peaks before/after post-hoc analysis based on area-based peak merging when cutoff 1=0.99

The number after pairwise post-hoc is the median value for all experiment pairs. For global alignment, cutoff 2 where all aligned compound have the same name is used, i.e., cutoff 2=10 (std.), =5 (mice) and =8 (wheat), respectively. The first number (before post-hoc) is the number of aligned peaks obtained by each method alone.
