Selected beta imaginary coherency graphs had positive signed scores in the next minute for all 19 SEEG patients
We tested whether beta spectral phase signs persisted in the next minute. We used public SEEG from OpenNeuro ds003876, version 1.0.2. A fixed sample had 19 patients with epilepsy. We selected the top 10 percent of eligible imaginary coherency edges in one minute, then tested their signs in the next minute. The primary analysis used the recorded reference and 13 to 29.5 Hz bins. All 19 patient signed scores were positive. Their mean was 0.04850. The 95 percent patient bootstrap interval was 0.02284 to 0.08200. The exact two-sided sign test gave p = 0.000003815 under independent patient signs with equal positive and negative probabilities. The mean patient ratio of test signed score to training absolute score was 0.2484. Mean selected-edge Dice overlap was 0.2835. Positive signed scores thus coexisted with changes in graph membership. We rebuilt all 4,222,800 Fourier coefficients from pinned public source ranges. A full analysis of the rebuilt inputs reproduced four result files byte for byte. The package preserves code, inputs, patient and edge results, figures, source hashes, and reproduction instructions. Earlier graph results informed this question. This is a new analysis of the same patients. Adjacent minutes, artifacts, and reference mixing limit the result. The score does not show information flow or causal neural connections.

The inherited sample selection, source metadata, range identities, and EDF helper originated in this work. We preserved its selection code and adapted its EDF helper through the beta graph parent. We did not use its high gamma results.

- usesMean overlap of top 10 percent beta graphs was 0.126 above the uniform contact shuffle mean within shaft groups across adjacent minutes in 19 selected SEEG records
This fixed input package supplied the 19 Fourier arrays, source metadata, raw examples, source range recipes, EDF helpers, and imaginary coherency function. Its known results informed the contact alignment question. We add an exact shaft group control and test its graph overlap baseline on the same patients.
- usesSelected beta phase signs gave positive scores in the next minute after adjacent contact subtraction in all 19 tested SEEG patients
We used all 19 Fourier inputs, three raw examples, source provenance, and the metadata and raw check code. Its contact-level signed result informed the new question. We tested a new adjacent contact montage with equal shaft pair weights on the same sample.
- usesA training amplitude cap at twice the median decreased the observed mean later beta coupling score in 19 public SEEG records
This work supplied the raw later signed score, the fixed 19-patient sample, the Fourier inputs, and source retrieval code. We compare a new training amplitude cap with the raw estimator. The patients are reused.
- usesPhase variance scaling gave mean Dice agreement of 0.265 compared with 0.309 for unscaled top 10 percent beta graphs in 19 SEEG records
Its signed strength analysis informed the secondary outcome. We selected edges and signs in one minute, then measured raw signed imaginary coherency in the other minute. This study uses squared imaginary coherency or the scaled score for selection.

The source retrieval script was adapted from its CC0 version-specific byte range retrieval code. It enabled fresh checks and exact reconstruction of all 19 Fourier inputs without a download of full EDF files.

Used its signed-score result as context for the question about agreement and common references. The present calculation uses the same cohort, complete matrices, and a different normalization.
