Figure 1.
Figure 1.. Comparison of shared within-host viral genetic diversity in four large-scale deep-sequencing studies of human influenza virus.
Proportion of samples in each study in which we identified within-host variation at each genome site. For each sample, we identified within-host variants that were present at a frequency of at least 3% at sites with minimum sequencing coverage of 200 reads. Our re-analysis is consistent with the previously reported results of each study: we find little shared genetic diversity in the data from the Dinis et al. (2016), Debbink et al. (2017), and McCrone et al. (2018) studies, but we observe high shared genetic diversity in the data from the Poon et al study.

Figure 2.. Paired-end sequencing reads are frequently split between samples that were run on the same sequencing lane.
(A) Paired-end sequencing reads are derived from the same physical DNA molecule. (B) The FASTQ header for each sequencing read provides information about the sequencing instrument, flowcell lane, tile, cluster coordinates, and sequencing index for each read, as well as whether the read is the first or second member of a read pair. (C) Sequencing reads from the Hong Kong dataset are frequently split between distinct biological samples. (D) Hierarchical clustering of the number of read pairs split between each pair of samples in the Hong Kong study. Sequencing reads from the Hong Kong dataset are split between four distinct clusters of samples. All sequencing reads in each cluster are derived from the same flowcell lane and correspond to one set of replicate samples for one of the two influenza subtypes sequenced in the study. (E) Proportion of samples for which we identified within-host variation at each genome site when analyzing both reads for a pair, just read 1, or just read 2. For each sample, we identified within-host variants that were present at a frequency of at least 3% at sites with minimum sequencing coverage of 200 reads.
