Taxonomic composition (best hit ratios) of the 16 unassembled datasets from the human gut viromes from Minot et al . (). Viral species are classified according to the NCBI taxonomy, and taxonomic groups can be folded or unfolded with a mouse click. Columns have been re-ordered through mouse drag and drop to gather datasets from each subject. Samples are named according to the diet (X: ad-lib diet, H: high fat/low fiber diet, L: low fat/high fiber) of 6 subjects (X, L1, L2, L3, H1, H2) and to the day of the sample collection after the beginning of the experiment (d1, d2, d7 and d8).
