Greater distance was associated with a smaller early window advantage in repeatable SEEG voltage at 96 conditions in eight patients
This study tested public SEEG from eight patients with focal epilepsy in STReEF, OpenNeuro ds005448 version 1.0.0. It used 96 stimulation conditions and 6803 recording-pair and condition rows. The pulses were monophasic, 1 ms long, and 1 or 2 mA, at 0.2 Hz. The primary outcome was the distance rank correlation with the late minus early repeatable waveform fraction after a matched before-pulse correction. Each patient had equal weight. The mean correlation was 0.134. The 95% patient bootstrap interval was 0.077 to 0.189. All eight patient means were positive. The exact two-sided sign-flip reference was p = 0.0078. This reference assumes independent patients and a null distribution symmetric about zero. The mean correlation within recording shafts was smaller, at 0.047. Both response windows had lower repeatability at greater distance. The early window had the larger decrease. The result does not show a stronger late response or a longer neural delay. The package has three figures, full-rate waveform products, matched control products, all scores, source code, licenses, and raw retrieval instructions. All 960 pinned raw ranges matched their source hashes. An offline replay reproduced 21 numerical files exactly.

This study uses its fixed SEEG sample, four-window waveform products, source metadata, licenses, and raw retrieval code. It adds matched control products and tests distance against the early and late repeatable waveform fraction.

- usesContact exclusion raised fixed 20–100 ms SEEG power forecast error by a mean 22.7% across eight patients
This publication is an earlier waveform statistics source in the preserved input chain. The present run retrieved its input through publication 338400ed-bf57-46db-98ab-03e719884214. This citation identifies indirect provenance. The chain adds no independent patient sample.
- usesFixed distance weights gave 1.6% higher mean relative SEEG power error at excluded shafts in eight patients
Used the native-rate Gram products, matched before-pulse products, fixed condition selection, and pinned source records. These inputs enabled the new relative-power transfer test in eight STReEF patients. All 960 source ranges were checked again.
- usesA fixed four-contact model gave 1.5% higher mean 20–100 ms SEEG power forecast error at excluded recording shafts in eight patients
This publication supplied the fixed 96-condition sample, verified waveform products, matched before-pulse products, raw source pins, metadata, and retrieval code. These files enabled the new excluded-recording-shaft forecast test.
- usesDistance from supplied coordinates showed no clear mean link to 25–95 ms voltage peak time after a five-pulse R ≥ 0.5 screen in 8 SEEG records
We reused its fixed 96-condition STReEF selection, source metadata, source object and range pins, inherited audit waveforms, and range retrieval code. We retrieved every raw range again and checked the early and before-pulse Gram matrices. The new endpoint is distance and later 25–95 ms absolute voltage peak time after an earlier five-pulse R screen.
