This analysis compares the principal coordinates analysis (PCoA) of UniFrac distance between samples for each platform, showing the best superimposition of one plot on the other. Samples in Roche 454 (orange circle) and Ion Torrent (green circle) are connected by a line. The blue line indicates Roche 454 samples and the red line indicates Ion Torrent samples. A lower distance between the circles indicates a higher degree of concordance between the plots.
