Additional file 6 of Proteobacteria explain significant functional variability in the human gut microbiome

Figure S7. Heatmap showing significantly variable and invariable gene families (unscaled). Heatmap showing residual log-RPKG abundances (i.e., after normalizing for between-study effects and gene-specific abundances) of significantly invariable (blue) and significantly variable (red) gene families. Variable and invariable gene families were clustered separately, while samples were clustered within each dataset. (PDF 158 kb
