Figure 7From: An integrated workflow for robust alignment and simplified quantitative analysis of NMR spectrometry dataPairwise Pearson correlation within the Wine dataset before and after alignment. Pairwise Pearson correlation coefficients between all spectra, for the different methods. Each dot within the heatmap corresponds to pair of spectra, with colors ranging from white (correlation = 0) to red (correlation = 1). The small inset on the top-left of each map is the histogram showing the distribution of the correlation coefficients and the value in its right side is the average correlation value.Back to article page
