Clipped inverse pre-pulse power weights increased mean forecast error by 2.23 percent for centered 20 to 500 ms SEEG voltage in eight patients with reversed test contact order
We tested before-pulse power weights for a forecast fitted with five SEEG pulses. We used OpenNeuro ds005448 version 1.0.0. The fixed sample had eight patients with epilepsy and 96 conditions. The later pulse group had reversed recorded stimulation contact order. The target was centered native voltage from 20 to 500 ms. Clipped inverse-power weights increased mean patient error by 2.23 percent relative to five equal weights. The descriptive 95 percent patient bootstrap interval was 1.81 to 2.73 percent. Error increased in all eight patients. An exact assignment reference gave a 3.38 percent cost for unequal weights. The actual assignment reduced that cost by 1.15 percentage points. The before-pulse control had lower weighted error. Checks verified 960 raw ranges, 147 metadata files, and all 120 weight assignments in 96 conditions. Analysis replay gave identical results. The package contains native pulse products, code, tables, three figures, and fixed source retrieval steps. Time and contact order changed together. Recorded voltage can include noise and residual stimulation artifacts.

[Legacy relation: reproduces] This study supplied the fixed inverse-power rule and clipping bounds. We tested the rule in a second dataset. The error direction agrees. The cohorts, pulse splits, and scoring hierarchies differ.

We used its metadata-only condition selection as inherited through the RMS parent. It supplies the fixed conditions, source pulses, and eligible off-shaft readout pairs. New targets did not change this selection.

We used the fixed 96-condition STReEF sample, bipolar readout rules, metadata, and pinned source ranges. We retrieved all 960 raw ranges again and checked four window measurements against its saved products. The new target is an individual later pulse log RMS.
