Figure 6

Correlation-based networks of Ain1 and Osl1. Network visualization of pairwise correlations of metabolites and lipids. The Pearson correlation was used to estimate correlation coefficients. Threshold tests for correlation coefficients (r) and p-values were applied to detect significant correlations. Thresholds were set tor r ≥ 0.8 and q of ≤0.05. Spurious correlations were removed, while significant correlations were transformed into network form. Metabolites are displayed as elliptical nodes and color-coded according to the compound classification; lipids are displayed as yellow elliptical nodes. Positive correlations are illustrated as blue edges, negative correlations as red edges. Communities in the networks were determined by the walktrap community detecting algorithm.
