Taxonomy, OTU (3% sequence distance) analysis and Unifrac results of the performed simulation.

<p>A) PCA results of matrix generated by sample distances based on classified sequence relative abundance (left) and presence absence (right) for the V regions and FL datasets. B) Similarly to A for OTU relative abundance (left) and presence absence (right). C) PCA results for matrices generated using the weighted (left - phylotype relative abundance based) and unweighted (right - phylotype occurrence based) Unifrac analysis result distances between samples for the V regions and FL datasets.
