Energy showed no clear AUC gain over waveform matching at 200–500 ms with early pair calibration in eight SEEG sessions
We tested a late response reader with public SEEG data from eight patients with epilepsy. The test used 86 stimulation sites. Five early good pulses selected one recording pair and fit a mean waveform. Pair selection used 20–500 ms during calibration. Five later good pulses tested each score at 200–500 ms. Both scores used the same pair. Mean AUC was 0.8334 for total energy and 0.8409 for signed waveform matching. The mean difference was -0.0075. Its descriptive 95 percent patient-bootstrap interval was -0.0627 to +0.0549. There was no clear energy gain. The result does not establish equal scores. An exact energy split gave projection AUC 0.8148 and residual AUC 0.7619. The template direction held 46.5 percent of later after-pulse energy. The residual can contain artifact, noise, and template error. AUC separates before and after labels; it does not prove a neural response. The package preserves code, figures, scores, source hashes, voltage samples, and a full retrieval recipe. The cohort was used in prior work, so the findings remain exploratory.

We read its split of energy into template projection and residual terms when choosing the method. The new test measures variance across later pulses with a matched before control. It does not repeat the detection AUC comparison.
- usesBefore-pulse energy showed no clear correlation difference between parallel and perpendicular slow SEEG template error after contact order reversal in eight STReEF patients
The comparison of waveform matching and energy motivated the distinction between error along a fixed waveform direction and perpendicular error. This study uses a different cohort and outcome. It does not use that publication's data or response-detection scores.
