Fig. 2From: metaSPARSim: a 16S rRNA gene sequencing count data simulatorSample-wise and feature-wise sparsity in real and simulated data. Q −Q plot of percentage of zeros in real and simulated datasets, calculated by sample (a, c, e) and by feature (b, d, f) for animal gut (first row), raw milk cheese (second row) and HMP (third row) data. R2 values are also reportedBack to article page
