Fig. 2From: Metaproteomics reveals persistent and phylum-redundant metabolic functional stability in adult human gut microbiomes of Crohn’s remission patients despite temporal variations in microbial taxa, genomes, and proteomesHeatmap illustrating the hierarchical clustering of the Spearman correlation coefficient between samples. Color represents the Spearman correlation coefficient between samples based on protein group abundance. Samples were hierarchically clustered using a Euclidian distance that was calculated based on the correlation coefficientsBack to article page
