Result

Precision (indel only, HG008 primary region) of Union of Mutect2, Strelka2 and DeepSomatic (at least one caller) (Hasan 2026) on NIST/GIAB HG008 tumour-normal WGS (HG008-T pancreatic cancer cell line, matched normal), HG008-T draft somatic small-variant benchmark v0.3

0.839 Precision (indel only, HG008 primary region)

Methods

Tested configuration: Union of Mutect2, Strelka2 and DeepSomatic (at least one caller) (Hasan 2026)
Protocol: HG008 primary region (nogermlineinterference), indels, Mutect2, Strelka2, DeepSomatic and ensembles (Hasan 2026 Table 2, Class 'INDEL')
Dataset: NIST/GIAB HG008 tumour-normal WGS (HG008-T pancreatic cancer cell line, matched normal), HG008-T draft somatic small-variant benchmark v0.3
Procedure: HG008 primary region (nogermlineinterference), indels, Mutect2, Strelka2, DeepSomatic and ensembles (Hasan 2026 Table 2, Class 'INDEL')
Evaluation: Union on HG008 primary region (nogermlineinterference), indels (Hasan 2026)

A source-checked result verifies the numerical transcription, not every model or protocol detail. Evaluation metadata: source checked. Source checked does not mean independently reproduced.

Reproduction

Split: External test; procedure frozen on HCC1395 before HG008 truth access
Adaptation: Not reported
Scoring implementation: Exact normalised CHROM/POS/REF/ALT match of PASS calls within the region

No execution recipe has been verified for this exact configuration and evaluation. A benchmark's general instructions may use different inputs, splits or model settings.

Reproducing this published result requires matching its model configuration, data, split and scorer. Source checking or a successful smoke test does not establish score reproduction.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Evidence table

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
