Figure 4

(A) PCA plot of 5 different samples of fish extract measured with technical replicates (10×) using NMR29. (B) Overlap of the average binned NMR spectra of the 5 samples: the two resonances whose correlation is investigated are highlighted (3.23 and 4.98 ppm). (C) Distribution of the correlation coefficient between the two resonances calculated, taking as input the average over different numbers of technical replicates (see inserts). See Material and Methods section 6.5.4 for more details on the estimation procedure.
