Five-pulse SEEG selection with a before-pulse score gave no clear 20 to 500 ms test gain in eight people
We tested whether a before-pulse score improves a five-pulse choice of a SEEG recording pair. Public ds004696 version 1.0.1 supplied eight epilepsy recordings, 317 conditions, and 1,183 candidate cases. Each rule selected from three or four adjacent-contact pairs with pulses 1 to 5. Pulses 6 to 10 tested the choices at 20 to 500 ms. The common test score was signed after-pulse repeatability minus before-pulse repeatability. Subtraction during selection changed 84 of 317 choices. The equal-person mean test gain was 1.05 score points. The descriptive 95 percent person bootstrap interval was -0.39 to 2.60 points. The mean after-pulse score decreased by 0.12 points; the before-pulse score decreased by 1.17 points. The main result gives no clear benefit. A planned 20 to 100 ms check gave a mean loss of 1.73 points. This secondary result is descriptive. The package preserves 7,098 pulse matrices, 31 native voltage examples, exact results, four figures, code, and verified raw retrieval recipes. All six result files reproduced byte for byte. Reused clinical records, small candidate pools, residual artifacts, and retrospective eligibility limit claims about new interface users.

The recording-overlap report supplied evidence for the cohort reuse limit. We use only ds004696 and do not count overlapping releases as independent cohorts. We did not repeat that audit.

This work supplied the exact metadata cohort, readout pool, source manifests, retrieval code, and numerical comparison data. We reused the cohort and rebuilt the raw pulse products. The new question tests a before-pulse term during readout selection, with a different test endpoint.

This study supplied prior context for selection with products of different pulses in another SEEG cohort and a recorded-current transfer task. We used it to state the scope of the new contribution. We did not reuse its numerical data.

We use its unchanged native pulse Gram matrices, voltage examples, condition records, source metadata, manifests, and extraction code. The new analysis tests chronological order in the actual final five pulses. We checked the inherited data hashes and made a fresh native audit in one fixed readout per person.
