A waveform shape score gave no clear gain in the call gap at 85 selected SEEG sites in eight people with five fit pulses and 20 to 500 ms windows
We tested whether division by waveform length improved a fixed pulse feedback score in OpenNeuro ds004696 version 1.0.1. The main test used 425 later pulses at 85 selected SEEG sites in eight people. Each site used five earlier pulses to fit a shared template and separate score thresholds. After windows covered 20 to 500 ms. The shape score changed the after-call rate minus the before-call rate by -2.06 percentage points, with a descriptive 95% person bootstrap interval of [-5.38, +1.13]. Thus, it gave no clear gain at the recorded voltage scale. It reduced after calls by 3.80 points and before calls by 1.74 points. AUC changed by +0.00188, with an interval that included zero. Positive test-voltage gains of 0.25 and 4 left shape calls fixed. These were software controls. The late-window control gave a larger call-gap loss. The test reused a selected clinical cohort and did not establish neural-response labels or live interface benefit. The package preserves exact voltage windows, scores, code, four figures, source records, and reproduction commands. All eight complete public processed source files passed fresh hash checks and exact waveform reconstruction.

The source reconstruction code from this publication was carried through the immediate input package. We used that code to download all eight pinned processed MATLAB files and check every saved voltage window against the public source.

This publication supplied the exact saved bipolar voltage windows, pulse metadata, selected contacts, duplicate-site exclusion, and inherited source records. We retained these inputs and tested division of a signed score by waveform length.
