Expected and observed pooled frequency estimates.

<p>Correlation coefficients between observed or simulated pooled allele frequency estimates and actual estimates as a function of the number of strains pooled. See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0041901#s2" target="_blank">Materials and Methods</a> for a description of the libraries. Y-axis: Expected (triangles) and observed (circles) correlation coefficients of the 7 libraries compared to a perfectly binomial library, color-coded by library. X-axis: Libraries ordered by number of strains pooled.
