Result

Kendall tau (of the cycle-closure-corrected absolute free energies, weighted mean over series, weight equal to compound count) of Second independent assay as the predictor on Repeat-assay affinity survey (Ross et al. 2023)

0.71 [0.65, 0.74] Kendall tau (of the cycle-closure-corrected absolute free energies, weighted mean over series, weight equal to compound count)

Methods

Tested configuration: Second independent assay as the predictor
Protocol: Repeat-assay reproducibility of relative binding free energies
Dataset: Repeat-assay affinity survey (Ross et al. 2023)
Procedure: Repeat-assay reproducibility of relative binding free energies
Evaluation: Independent repeat affinity assay on the repeat-assay survey
Coverage: Not reported scored / Not reported eligible
Uncertainty: 95% CI 0.65 to 0.74. 95% confidence interval from bootstrap sampling over the pairs of experimental series or FEP+ graphs (Table 3 legend)
Evidence: Author-reported evaluation · source checkedThe maximal and current accuracy of rigorous protein-ligand binding free energy calculations · Table 3, row "Kendall τ", column "Experimental survey"

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: Whole collection; the assessed workflow is not trained
Adaptation: Not applicable: a second independent assay is used as the estimate
Scoring implementation: Pairwise errors over every ligand pair in a graph; edgewise errors over the graph's edges; R2 and Kendall tau of the cycle-closure-corrected absolute free energies (Methods, 'Accuracy metrics')

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.

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.
