Kraken2 · L1 abundance error · HumanGut-all strain-level query

Tested configuration: Kraken2
Task: Strain-level abundance quantification
Dataset: HumanGut-all strain-level query
Procedure: Strain-level quantification on the HumanGut-all synthetic query.
Evaluation: Kraken2: Strain-level abundance quantification
Coverage: scored: unreported; eligible: unreported
Uncertainty: Not reported
Evidence: Independent external evaluation · source checkedStrain level microbial detection and quantification with applications to single cell metagenomics · Table 5, B. L1 Err. / HumanGut-all row, Kraken2 L1 Err. column

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

Reproduction

Split: Not reported
Adaptation: Not reported
Scoring implementation: Not reported

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.

Access requirements and official instructions: Strain-level abundance quantification

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.
