Figure 3From: A joint analysis of metabolomics and genetics of breast cancerHierarchical clustering of metabolites based on correlation coefficients. The correlation coefficients were calculated using Pearson product-moment of each pair of metabolites (log base 2 normalized) among 399 metabolites from 25 breast cancers and 5 normal breast tissues. Eight clusters of highly correlated metabolites are highlighted on the right panel.Back to article page
