Division by before pulse variance replaced 13.2 percent of top ten percent SEEG links on average in five patients with ten pulses per site

We tested whether division by before pulse variance changes the strongest SEEG link lists. We used OpenNeuro ds004457 version 1.0.2. The fixed selection contained 1,080 links from five patients. Each patient had eight receiving contacts. Each site had ten selected pulses. We measured an absolute after minus before waveform energy contrast. We compared it with the same contrast divided by before pulse variance. The top group contained ten percent of each patient's links, rounded up. Division replaced a mean 13.22 percent of each original group. The descriptive 95 percent patient bootstrap interval was 7.27 to 20.93 percent. Every patient had a replaced link. Energy correction replaced a mean 2.11 percent within the absolute scale. It replaced 1.00 percent within the divided scale. Three sensitivity checks gave normalization replacement means from 14.79 to 15.00 percent. This informed extension used the same pulse data as cited earlier energy studies. It does not establish which score has greater biological accuracy. The small clinical sample limits population claims. All 120 raw source files passed their hashes. Every archived input array was rebuilt exactly. Fourteen analysis output files were reproduced. The package preserves pulse windows, source code, metadata, proofs, results, figures, citations, and reproduction instructions.
