An illustration of replacing value of 0 with value of 1, the total Shannon diversity plot, Rand index plot, and the PCoA plots of the modified MartÃnez datasets. A A schematic plot illustrates how we increased the low-abundance OTUs by replacing value of 0 with value of 1. B The total Shannon diversity increases with the number of 0 entries replaced with 1. C Rand index of the MartÃnez dataset with an increasing number of 0 entries replaced with 1. D Unweighted UniFrac beta diversity PCoA of MartÃnez dataset with 0%, 40%, and 60% of 0 entries replaced with 1
