Figure 3

The data was compared to KEGG database using a maximum e-value of 1e−5, a minimum identity of 30%. The heatmap was clustered using ward clustering with Canberra distance metric and grouped at level 2 of KEGG annotation. The shading is proportional to the normalized values (0–1) calculated on the functional enrichment of each category per sample.
