Quick reference for definitions of variant categories defined and used frequently throughout this study

Variant categoriesOther namesDefinition
Common ground truthWGS variantsVariants derived from WGS
Pooled readVariants derived from pooled-read bulk calling on single-cell sequencing
Individual-cell variantsVariants derived from individual-cell calling on single-cell sequencing
Pooled true positiveTPPooled-read variant that has a matching WGS variant
Pooled false negativeFNWGS variant not detected in pooled-read variant calling on single-cell sequencing
Rare positiveRPVariant that was detected in single-cell sequencing that was not present in the common ground-truth set
Union of rare positive (URP)scRNA-RP/scATAC-RPUnion of rare positive variant calls for all callers performed on pooled scRNA-seq or scATAC-seq reads
Multimodal rare positiveMRPURP variants seen in both scATAC-seq and scRNA-seq modalities
Single-cell-unique (scu)scRNA-scu/scATAC-scuVariant detected at the single-cell level in single-cell sequencing that was not called on pooled reads nor found in WGS
