Figure 5.
Comparison of taxonomic profiles from microarray and sequencing data. Each column represents one patient sample; each row represents a taxonomic group. Samples are labeled by subject (subjects 1–3) and by anatomical site (C: cecum; T: transverse colon). Both microarray data (Cy5/Cy3 ratios) and sequencing data (clone counts) have been converted to a fractional abundance scale. (A) Relative abundance estimates are shown for all taxonomic groups represented by at least 1 probe with well-measured reference signal. (B) Expanded view of an arbitrary subset of species-probe data. Bold font indicates species whose presence was confirmed by PCR. Asterisk indicates averaged microarray values from two replicate PCRs.
