Selected beta phase slope signs had lower mean agreement across adjacent minutes than across two references in 19 SEEG records
We tested beta phase slope sign agreement in 19 public SEEG records from OpenNeuro ds003876 version 1.0.2. Each patient supplied two adjacent minutes. We selected the strongest 10% of eligible contact pairs in each recorded-reference minute. We compared their signs across minutes and across the recorded and common average references in the same minute. Patients had equal weight. Mean agreement was 55.86% across minutes and 81.76% across references. The mean difference was -25.89 percentage points. Its 95% patient bootstrap interval was -31.60 to -19.88 points. The difference was negative in 18 patients. The exact sign-flip p value was 0.0000076294. This test assumes independent patients and symmetric null patient contrasts. Fixed selection and clipping checks retained the same direction of the mean gap. The comparisons share different amounts of data. They cannot separate sampling error from brain changes. Raw PSI ranks do not establish significant neural connections or causation. The package preserves all inputs, pair values, code, source versions, hashes, checks, and reproduction instructions. Fresh public source bytes reproduced all 19 compact inputs and all 24 numerical result files exactly.

This work produced the compact Fourier inputs and fixed the full eligible pair rule. Its recorded and common average reference results helped define the new sign agreement question.

Its metadata selection and EDF extraction code supplied the inherited data methods. The package preserves its original metadata selection program and uses its EDF helper through the immediate input publication.

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.

- Timing margin ranking gave 52.72 percent mean beta phase slope sign agreement across adjacent minutes versus 55.86 percent for raw ranking in 19 SEEG patients at 10 percent pair density
[Legacy relation: reproduces] The raw-ranking baseline was repeated in the same 19 patients. Mean agreement was 55.863563 percent at 10 percent density. The patients are reused; this is not independent patient replication.

This work supplied the raw PSI ranking and adjacent-minute agreement endpoint. We retained both selection directions and equal patient weights.

This publication supplied the 19 compact Fourier inputs, raw phase slope code, source checks, and raw agreement benchmark. The new comparison reproduces that benchmark and tests selection by jackknife precision on the same clips.

We used its 19 ds003876 Fourier input files, source metadata, pinned range recipes, selection audit, and EDF helper. We checked all input hashes and rebuilt every Fourier value from fresh public source ranges. The new endpoint uses the same patient sample. It is not an independent cohort replication.

We used its fixed 19-patient sample, compact Fourier inputs, source provenance, helper code, and known raw-ranking result. Its patient table verified our raw baseline. The new test compares jackknife ranking with that raw rule.
