Cluster size versus frequency plot. The log10 of the cluster size (logCt) (i.e. number of sequences in each cluster) plotted against the log10 of the frequency of cluster membership sizes (i.e. the frequency of clusters that contained n sequences, where n is the cluster membership size) found among all mock community samples. Plots of all mock community data (a), data with cross-sample singletons removed (b), and data with both cross-sample singletons and doubletons removed (c) are shown. Red line regression line, blue line lowess fit line, SE standard error, r2 coefficient of determination
