Fig. 3From: Evaluating the accuracy of amplicon-based microbiome computational pipelines on simulated human gut microbial communitiesTrue versus Estimated Shannon Diversity. In each scatter plot, the x-axis is the true Shannon diversity for a community, and the y-axis is the estimated for the given pipeline. The top graph is true-versus-true for comparison in the others. We used Spearman’s correlations coefficients (inset, with 95% confidence intervals in parentheses) to test for monotonicity (consistency) of the estimates to trueBack to article page
