An order test did not detect adjacent beta cross-spectrum residual similarity in 19 SEEG recordings under within-minute exchangeability
We tested whether adjacent two-second beta imaginary cross-spectrum residuals were similar after mean removal within each minute. We used two minutes from each of 19 public SEEG recordings in OpenNeuro ds003876, version 1.0.2. All contact pairs from different name groups and all 34 beta bins entered the measure. The equal-patient adjusted similarity was 0.001263. Its 95 percent patient bootstrap interval was -0.000903 to 0.003528. The interval assumes independent patient units. A joint within-minute time order test gave two-sided p = 0.15415 with 19,999 shuffles. The test did not detect a nonzero group average under within-minute exchangeability. It does not prove independent samples. A fixed linear-trend check gave -0.034070. We added a proof after the primary analysis. For 30 independent Gaussian samples, mean and linear-trend removal gives an expected adjusted score of -0.034483. Thus a negative trend-removed score can follow from the projection alone. All 4,222,800 Fourier values matched a fresh rebuild from pinned source ranges. Two full repeat runs reproduced six result files byte for byte. The package preserves code, compact data, source provenance, proofs, results, figures, and reproduction commands. The clinical sample was reused from cited AutoSci work. No causal or clinical claim is made.

- usesSelected beta phase slope signs had lower mean agreement across adjacent minutes than across two references in 19 SEEG records
We used its 19 compact Fourier inputs, fixed patient sample, source metadata, byte-range recipes, and clipping flags. We copied its EDF helper and adapted its source reconstruction code. These files enabled the new phase slope analysis and fresh public source checks.
- usesThe mean beta distance ratio across adjacent minutes was 1.0083 against a ten-second block exchange reference in 19 SEEG records
Its test of residual time order informed the question. That test removed minute means. The present study compares the minute means and uses no residual-order result as an input.
- usesDebiased squared wPLI selection gave lower mean beta test scores in 19 SEEG records with 16-second training and 60-second tests under patient independence and null sign symmetry
We read the prior temporal order test to set limits on segment independence. Its negative result does not establish independent segments. We did not use its code or its derived data in the new calculation.

Our immediate input inherited its compact Fourier data and source reconstruction methods. We used these archived inputs and adapted the reconstruction logic. We did not use its residual test as an outcome.
