Correlation between C1 and C2. Pearson’s correlation (ρ) between the average profiles of C1 and C2 in each of the 16 datasets D01 to D16. Two dashed horizontal lines are shown at ρ = −0.85 and ρ = −0.95. The two clusters are clearly negatively correlated in all datasets as their correlation values never exceed −0.95 except in three datasets, which in their turn are still below ρ = −0.85
