Functional analysis of metagenomic data. Top panel: SEED level 1 categories for which all BF or all FF samples had at least
200 reads mapped. At least 2% of the total number of mapped reads were tested for
differences between BF (breast-fed) infants (green) and FF (formula-fed) infants (blue).
A permutation test on the test statistic ∑_{iεBF }p_{i}/6 - ∑_{iεFF }p_{i}/6, where iεBF and iεFF denote that sample i is BF or FF infant, respectively, and
p denotes the associated taxon proportion, was performed. The FDR corrected q-value
for the virulence category was 0.058. Bottom panel: differences between BF and FF
infants in the SEED level 2 virulence assignment (within the SEED level 1 virulence
category) was assessed using a permutation test on the test statistic ∑_{s }|∑_{iεBF }p_{is}/6 - ∑_{iεFF }p_{is}/6|, where s indexes the SEED level 2 virulence categories, and P = 0.0140.
