Fig. 2

Relative abundances of the 33 bacterial species in the mock community sample estimated from both the MiSeq (dataset 1, n = 96) and HiSeq (dataset 4, n = 24) data (Additional file 4: Table S3, Additional file 7: Table S6). Species abundance estimates are shown side-by-side with MiSeq estimates labeled ‘MS’ and HiSeq estimates labeled ‘HS’. For enhanced visualization, each pair of colored bars (blue or white) depicts the estimated relative abundances for one species. The dotted red line shows the relative abundance expectation given perfectly equal blending. Each box represents the interquartile range while the whiskers represent 1.5 times the interquartile range. Points outside the whiskers represent outliers
