Somatic Variant Calling Workflow. Illustrates a detailed workflow of the somatic variant calling process. The steps from “Transpose to pileup” and below are performed by the lumosVar software. (PNG 151 kb

Definition of True Variants. Describes the criteria for counting a variant as a true variant. Germline variants were called by haplotype caller, samtools, and freebayes. Somatic variants were called by Mutect, Seurat, and Strelka. (DOCX 15 kb

Copy Number and Sample Fraction Across Dilutions. The copy number (left), minor allele copy number (center) and sample fraction of the copy number events (right) are plotted as heatmaps. (PNG 35 kb

Variant Quality Filtering Across Dilutions. Shows the number of variants of each type, in each quality filtering category. Each graph represents a variant type, each bar represents a dilution, and the color of the bar represents the number of variants in each quality category. High quality positions have a PT > 0.99. Low quality positions have a PT < 0.99 but PV > 0.99. Artifacts have a PV < 0.99 and non variants are not considered by the tumor only caller (NaN). (PNG 43 kb
