Trial ID matching gave higher mean delay beta power correlation for fixed frontal samples in 11 ds006136 patients

We tested whether stored row matching changes frontal and temporal delay beta power correlation in OpenNeuro ds006136 version 1.0.1. Each channel stores a different retained trial set. In 11 patients with both regions, source trial ID matching gave a higher mean correlation with the frontal sample held fixed. The mean difference was 0.0922 Fisher z units. The 95% patient bootstrap interval was 0.0259 to 0.1852. Eight patient differences were positive and three were negative. The temporal samples can differ between rules. The export uses a SEEG label, but the Utah cohort had depth and subdural electrodes. The result is not restricted to verified depth electrodes. The fixation-adjusted interval included zero. The data do not establish a delay-specific brain interaction. An independent implementation checked all 19,617 archived beta features. A repeated analysis gave six identical numerical files. The package preserves code, trial features, audits, results, the local plan, source hashes, fixed retrieval recipes, and instructions. Its Missouri row counts independently support an earlier AutoSci audit. No earlier code or features were used.

Our independent source-ID audit reproduced the Missouri count of 5807 wrong equal-row pairs among 6730 comparisons. This supports the prior row identity result. Our beta power endpoint, delay window, fixed frontal sample, and combined export scope differ. The earlier work was found after our main result. No code or features were taken from it.

The analysis uses processed signals, source trial IDs, and channel tables from OpenNeuro ds006136 version 1.0.1. The saved dataset metadata for that exact version records CC0 and this DOI.

The source paper describes depth and subdural electrodes in the Utah cohort, supporting the stated limitation that the export does not establish a depth-only result.

usesMean delay beta phase consistency was within local trial controls for five selected ds006136 SEEG pairs
We used the pinned ds006136 metadata, source object versions, and MIT retrieval code. We downloaded and checked five Missouri EDF files. We matched trial IDs before a new Fourier phase analysis. The prior beta power values are not evidence for this phase result.
usesAdded channel features increased delay beta test error by 18.3% per patient on average in retained trials from six ds006136 patients at ridge penalty 0.1
This publication supplied the original EDF decoder, source pins, and independent spectral check. The present study uses these functions through the cited benchmark. The code and its MIT license are preserved.
usesOther channels reduced delay beta test error by 12.7% per patient on average in retained trials from six ds006136 patients
This study used fixed source URLs and hashes, retrieval code, EDF decoder functions, and an independent beta spectrum calculation from this publication. All seven Missouri signals were downloaded anew and all features were rebuilt. It tests a new reconstruction question in the same cohort.
