Comparison of the clustering of variants across platforms.

<p>The ten most common nucleotide V3 sequences from samples 10–172, 10–176, and 10–180 -obtained with each of the four NGS platforms (454™, Illumina®, PacBio®, and Ion Torrent™)- were aligned against the respective population (sanger) sequence and analyzed as described in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049602#pone-0049602-g004" target="_blank">Figure 4</a> legend.
