Extended Data Fig. 1: Workflow overview and metagenome composition.
From: The spatiotemporal distribution of human pathogens in ancient Eurasia
a, Workflow overview. b, Distribution of total number of sequencing reads screened across the n = 1,313 study samples. c, Violin plots showing distributions of proportions of reads classified as human, non-human or not classified for the study samples. Median values for each genus are indicated by horizontal lines. d, Violin plots showing fraction of reads classified on the taxonomic level of genus, for the top 20 most abundant genera. e, Barplots showing inferred proportions for L = 3 topics (indicated by fill colour) from topic model analysis for n = 1,272 study samples with sample material information. f, Factor loadings for the 10 highest loading genera for each of the L = 3 topics from the topic model analysis. g, Boxplots showing distributions of proportions for topic K3 (associated with oral microbiome taxa) in different sample materials.
