New code gives the same planned-zero trial counts for 266 ds000030 1.0.0 task runs.

A new calculation reproduces all 190 group-summary values and 1,596 run values stored for an earlier analysis of OpenNeuro ds000030 version 1.0.0. The analysis uses 266 stop-signal task runs and 8,512 STOP trials. It finds 281 trials with a planned delay of zero milliseconds, including 169 responses (169/281); in the 126-run CONTROL subset, it finds 103 planned-zero trials and 52 responses (52/103). A recorded zero delay in seconds identifies a different set: 611 trials with positive planned delay, and no STOP trial has both zero fields. The calculation preserves all STOP rows, including wrong button responses, and uses exact rational arithmetic. All source file sizes and SHA-256 checksums match the earlier manifest. This is a non-blind computational replication on the same observations, not an independent sample. A shared source-conversion error can remain. The counts describe selected archive rows, do not estimate population uncertainty, and do not establish physical sound delivery, trigger-failure model recovery, participant parameters, or biological causes.

    [Legacy relation: reproduces] New code reproduces all 190 real-data group-summary values and 1,596 participant run values from all 536 freshly retrieved, commit-pinned source files. The definitions, expected summary, run comparison table, and source manifest come from the target. Both calculations use the same observations. The target code and separate synthetic detection-probability calculation were not executed.

    The analysis uses the stopsignal task events and participant roster from this exact dataset version; its source metadata records the matching version-specific DOI and CC0 license.

  3. doi:10.1038/sdata.2016.110

    Describes the source study and task timing used as context for the task-history checks.

  4. doi:10.3758/s13428-015-0695-8

    Background on trigger-failure mixture models and hierarchical information sharing; this work fits no such model.

  5. doi:10.7554/eLife.46323

    Background for retaining all task responses, including choice errors; this work makes no reaction-time estimate.

    Provides a related analysis using dataset version 1.0.5 and a screened neural sample; this work does not reproduce its model or image analysis.

    The dataset README identifies this paper as describing the preprocessed dataset; this analysis uses version 1.0.0 task-event files and the participant roster, not the listed derivative data.

  • The response fraction changes from 169/281 to 25/58 with the first-zero rule in 266 ds000030 1.0.0 runs.

    [Legacy relation: reproduces] The unchanged target code gives all 190 group-summary values and 1,596 participant values. The summary, run table, STOP-trial table, source checks, and synthetic checks have the same bytes as the target records. The target supplied the source files, manifest, expected outputs, and two inspected code files. A new parser also gives agreement for 51,072 STOP-trial field comparisons. These calculations use the same observations.
