Extended Data Fig. 2: Summary of virome sequencing of infant stool.

a, Heat map summarizing the representation of the top five most-abundant DNA viral contigs in each sample. Samples are grouped sequentially by infant on both the x axis and y axis. The last group of infants on the x axis are negative control samples. Circularity indicates whether a contig is circular (orange colour) or not (light-green colour). The heat map map colour represents the abundance (log-transformed reads per million total reads) of each contig in each sample. b, Contig read abundance compared between different infants and within the same individuals. Time points were pooled for each individual. c–e, Percentage of DNA virome reads assigned to viruses (c), unassigned (d) and contamination (e). f–h, Percentage of RNA virome reads assigned to viruses (f), unassigned (g) and contamination (h). b–h, n = 20 infants at three time points were tested. The horizontal lines in box plots represent the third quartile, median and first quartile; whiskers extend to ±1.5× the interquartile range. The dots represent the outliers.
