Fig. 3

Simplified illustration of the benchmark of the virus identification pipeline (TELEVIR) module components, which is described in detail in Additional file 1. A Tree representation of module combinations. From left to right, sections represent pipeline steps (exemplified for Illumina) as followed at runtime: (1) Quality Control, (2) Viral Enrichment, (3) Assembly, (4) Contig Classification, (5) Read Classification. Nodes represent software, parameters, or databases compared. Color gradient corresponds to the product of four assessment statistics: mapped reads proportion, horizontal coverage, true positive rate, and completeness (proportion of hits with both read and contig evidence). Statistics were standardized by their respective maxima. B Heatmap representation of software benchmarked for Illumina samples, parameters not discriminated, color code at the bottom. C Table of individual statistics for each node, standardized across samples as in A. For panels A and C, darker colors = lower values, lighter colors = higher values
