Figure 1From: Model-based peak alignment of metabolomic profiling from comprehensive two-dimensional gas chromatography mass spectrometryExperiment I: KDE plots before/after peak alignment for homogeneous experiment (dataset3). Top: kernel density estimate (KDE) corresponding to the first retention time before (left)/after (right) peak alignment. Bottom: kernel density estimate of the second retention time before (left)/after (right) peak alignment.Back to article page
