Figure 4

Untargeted analysis of TMA2 using full scan mass spectral data acquired in the negative ion mode. (a) Unsupervised clustering by estimated TCP was observed after PCA in the two-dimensional space generated with the first two principal components estimated (68% variance explained). (b) Observed separation between both groups is primarily associated with the first principal component (44% variance explained).
