Fig. 4. — Correlation analysis of pair-wise comparison of metabolite time series. A Pearson correlation coefficient was calculated for each pair of conditions based on the positive or negative correlation between the metabolite profiles over the entire light–dark cycle. The Pearson correlation coefficient ranges from –1 (blue) to 1 (red), with –1 indicating higher negative correlation and 1 indicating higher positive correlation between the two compared data sets.
