Fig. 2From: Revised computational metagenomic processing uncovers hidden and biologically meaningful functional variation in the human microbiomeFiltering prevalent gene families increases functional variability. Shown are the distributions of pairwise Bray-Curtis distances in the pathway-level abundance profiles between different samples of the gut microbiome, including all gene families (red), or excluding all genome-prevalent (green), or excluding gut genome-prevalent (blue) gene familiesBack to article page
