Figure 10.

Topological maps of (A,C) primary metabolites as well as (B,D) secondary metabolites and lipids based on experimental data in proximity to resolved compartments. All graphs depict classification results visualized in principal coordinates (PCo) space on the basis of averaged normalized Euclidean distances among metabolites for the three independent gradients. (A,B) Chemical superclass assignments were overlaid on structurally identified metabolites and (C,D) k-medoids cluster assignments (cf. Krueger et al., 2011) were overlaid on all metabolites.
