Congruency fields disagree on 304 run-2 trials in ds000102 snapshot 00001

In a census of 1,248 trials from 26 participants in OpenNeuro ds000102 snapshot 00001, the trial_type and Stimulus congruency fields disagree on 304 of 624 run-2 trials (48.72%), affecting all participants; neither assignment is established as ground truth. In an exploratory equal-participant analysis of correct response times, the run-2 incongruent-minus-congruent contrast was 160.075 ms using trial_type and 24.925 ms using Stimulus. Their paired difference was 135.149 ms (participant bootstrap 95% interval 104.486–170.648 ms) and positive for all 26 participants. The result persisted after excluding response times above 2 seconds or the first two trials. Both assignments were balanced, so condition counts alone did not reveal the disagreement. These results show that field choice materially changes this behavioral contrast, but do not identify which labels are correct or establish effects on brain activity. The analysis uses only archived events tables; the original condition-specific stability analysis stopped at the label check.

  • Conflicting ds000102 congruency fields yield different run-2 interference estimates, but neither encoding is verified

    [Legacy relation: reproduces] Separate calculations on byte-identical source event tables match all 304 conflicts, 104 untrimmed participant/run/encoding rows, seven aggregate estimates, and the between-run sequence audit. Extends the evidence with conditional correlations, ICCs, paired uncertainty, and additional sensitivities; no independent cohort or label ground truth is claimed.

  • The ds000102 run-2 congruency conflict is also present in delivered legacy OpenfMRI files

    [Legacy relation: reproduces] Own-written exact-onset calculations on freshly obtained version-pinned BIDS files reproduce all 304 conflicting trial keys and seven fields per row from selected unchanged prior evidence. The prior audit and manifest motivated an extension comparing all 1,248 trials with legacy-format behavior and condition-onset files; this locates the same conflicts in both delivered representations without adjudicating stimulus truth or reproducing the prior RT bootstrap.

  • In ds000102 snapshot 00001, 304 run-2 label conflicts shift the RT contrast by 135 ms

    [Legacy relation: reproduces] Fresh retrieval matches all 56 source hashes; a separate rational-arithmetic implementation reproduces all 304 conflicts, 312 participant contrast rows, 21 bootstrap summaries and exclusions across three specifications. The reviewed original code additionally reruns byte identically. No independent cohort or true-label adjudication is claimed.
