Dispersion of the variants relative to the representative sequence of each cluster.

<p>Box-and-whisker diagrams showing the dispersion of the variants relative to the representative sequence in each cluster of the P7 (A) and P3 (B) libraries. For each cluster, the blue box contains 50% of all of the sequences in the cluster. The red line shows the median of the number of mutations relative to the representative sequence of the cluster, and the little red crosses represent outliers of the cluster.
