a, Total bases searched from the 5,686,715 SRA sequencing runs analysed in the viral RdRP search grouped by sample taxonomy, where available (see Extended Data Figs. 1, 3, Supplementary Table 1). A total of 8,871 out of 15,016 (59%) of known RdRP sOTUs were observed in the SRA, and 131,957 unique and novel RdRP sOTUs were identified (see Extended Data Fig. 2). sOTUs identified in multiple taxonomic groups are counted in each group separately; numbers shown indicate the number of novel sOTUs in each group. WGS, whole-genome sequencing. b, Release dates of the runs included in the analysis reflecting the growth rate of available data. c, Sample locations for 635,656 RdRP-containing contigs (27.8% of samples lacked geographical metadata). The high density of RdRP seen in North America, western Europe and eastern Asia reflects the substantial acquisition bias for samples originating from these regions.
