This Article contains an error in Figure 5, where the Negative mode heat map is a duplication of the Positive mode heat map. The correct Figure 5 appears below as Figure 1.
Figure 1.
Heat maps (top) and PCA plots (bottom) of metabolites extracted by the elastic net regularized Poisson regression (glmnet) model over the time series in both positive and negative modes. The elastic net model extracted 32 metabolites of interest in both ionization modes.
