FIGURE 3.
Volcano plot of KEGG Orthology abundances obtained from metagenomic simulation. Fold change of United States (A), France (B), and Saudi Arabia (C) of KO abundance with regard to Chile are plotted against –log10 of FDR. Dotted lines in the x-axis denotes a two-fold change, while dotted lines in the y-axis delimit a FDR value of 0.05.
