Mean ordinal pattern agreement is positive across paired 1–25 Hz SEEG records from 36 epilepsy patients
We tested whether three-point voltage patterns had the same time direction in two interictal SEEG records. We used public OpenNeuro ds004100 version 1.1.3. We selected one common bipolar pair per named depth electrode in 36 epilepsy patients. Each record supplied 60 seconds at 1–25 Hz. The sample lag was 31.25 ms. The mean agreement was positive. Its patient bootstrap interval did not include zero. The mean dot product of signed pattern differences was 0.000237434. The descriptive 95 percent interval was 0.000159681 to 0.000329708. There were 453 selected pairs. Each patient had equal weight. We generated 39 IAAFT controls per signal. These controls kept all voltage values and approximately kept the spectrum. The mean recorded-minus-control agreement was 0.000240591. The package preserves compact signals, code, source hashes, all control counts, results, and checks. The result concerns these selected recordings. It does not identify a neural cause or a clinical marker.

- usesContact order changed half-strength ordinal prediction gain in paired 1–25 Hz SEEG from 36 epilepsy patients
We reused all 36 paired signal arrays, archived ordinal control counts, metadata, pinned retrieval records, and source code. We verified every archived file hash and recalculated all observed ordinal counts.
- usesOrdinal maps at half strength reduced mean relative prediction error in paired 60 s 1–25 Hz bipolar SEEG from 36 patients
This study uses the exact processed SEEG signals, original ordinal and IAAFT counts, pinned raw retrieval code, metadata, and source hashes. It adds a source-only prediction test against patient mean patterns.
- usesMean time pattern agreement was positive between two 56-second 1-25 Hz SEEG intervals in 19 patients with epilepsy
We used the fixed signed ordinal vectors, agreement score, IAAFT code, and signal processing choices. We tested two intervals per record in another dataset.
- usesMean order agreement exceeded spectral controls in paired rest and film SEEG excerpts from nine adults with epilepsy
Its signed ordinal agreement measure and result in paired SEEG records from ds004100 supplied the research question. We tested that principle in ds003688 with paired rest and film records, four fixed lags, and common-phase spectral controls. We did not import its signals, scores, or code.
- usesMean time pattern agreement stayed positive after a voltage mask with 0.5-second margins in eligible 1–25 Hz SEEG from two epilepsy cohorts
We used the saved 36-patient HUP voltage arrays, selection rules, extraction code, and pinned source records. We checked its full pattern counts before the new voltage mask analysis.
