Correlation network for different pathways. Nodes representing metabolites (green), enzymes (orange) and morphological or other parameters (gray) are laid out as circles for each pathway. A n:n correlation was calculated, resulting in edges indicating a strong (p≥0.95) correlation, color-coded by the r-value. This visualization enables an overview about intra- and inter-pathway dependencies.
