Fig. 3. Pearson’s correlation coefficient matrix of the Z-scores of 18,583 peptide substrates cleaved by MMPs.

Fig. 3

The bottom triangular matrix shows raw correlation coefficient. The top triangular matrix represents a degree of correlation in a form of an ellipse (a low minor axis denotes a high correlation). The color of the coefficient and ellipse also indicates the correlation strength to aid the eye. Cyan indicates low correlation (0 – 0.3), blue denotes medium correlation (0.3 – 0.8), while red denotes high correlation (0.8 – 1) among the MMP cleavage preferences.
