Fig. 3

Relative abundances of each mock community member and the unmapped reads with the exception of Nocardiopsis dassonvillei (too few sequences mapped to reference). Individual GC plots corresponding to the high and low GC references are displayed in Additional file 1: Figure S1, which further illustrates the shift in relative abundance from low to high GC organisms across the dilution series. Unamplified control library is represented by the red diamond
