Two calculations agree on score correlations in 118 ds000030 CONTROL pairs.

We repeated a paired analysis of stop-signal reaction-time scores from 118 CONTROL participants in OpenNeuro ds000030 version 1.0.0. We compared recorded, planned, and hybrid stop-delay rules across training and scanner runs. Pearson correlations were 0.515542, 0.583641, and 0.580057; Spearman correlations were 0.488136, 0.567539, and 0.567101. The recorded-minus-planned differences were -0.068099 for Pearson (95% bootstrap interval [-0.177917, 0.036182]) and -0.079403 for Spearman ([-0.215491, 0.052292]); both intervals include zero. In all 126 complete pairs, the Pearson difference was -0.048613 ([-0.133880, 0.009684]). These results do not establish a population decrease, equal correlations, or which delay field represents acoustic onset. The score is an arithmetic estimate under model assumptions. The runs share participants and training staircase history, each has 32 STOP trials, and the comparison does not establish independent test-retest reliability or a biological effect.

    [Legacy relation: reproduces] The separately written calculation uses the same 118-pair sensitivity sample and 126 complete pairs. Exact identifiers and 68 summary cells agree within 1e-9. This includes selected 118-pair intervals and point values for both samples. The 107-pair primary sample and 126-pair intervals are outside the reproduction scope.

    [Legacy relation: reproduces] Its inspected three-delay estimator and authenticated comparison table enabled a scanner check. New code reproduces all 378 scores and the strict 102-run selection. Its uncertainty intervals are outside this reproduction scope.

    [Legacy relation: reproduces] Its hash-checked public inputs and source manifest enabled the local analysis. All 258 files were then verified from the pinned upstream. New code reproduces 759 scores and all 253 screen_10 decisions. Its code was read as text; it was not executed or imported.
