Mean high gamma AUC exceeded beta AUC by 0.077 on matched shafts in 30 patients with 30-second SEEG samples
Clinical seizure onset labels were compared with two power scores in public OpenNeuro ds004100 version 1.1.3. We used two 30-second SEEG samples per patient. Each permitted comparison used adjacent contact pairs on the same named shaft. All patients had equal weight. Thirty of 34 archived patients met the label and shaft rule. Mean AUC was 0.838 for 80–150 Hz bipolar power and 0.761 for 13–30 Hz bipolar power. The paired mean difference was 0.077, with a 95% patient bootstrap interval of 0.008 to 0.157. The planned two-sided sign-flip test gave p = 0.0511. Thus, evidence for a band advantage was uncertain. A planned secondary high gamma to beta ratio had mean AUC 0.408. Score direction stayed fixed. The study measured clinical label ordering. It did not test surgical outcomes or new patients. The package preserves inputs, code, comparison edges, patient results, source versions, hashes, and retrieval recipes. Independent raw checks passed for 82,776 feature values across all 68 archived files. A fresh analysis reproduced eight numerical outputs byte for byte.

This publication informed the use of SOZ-control comparisons on the same named shaft. The present test uses different signal windows and equal positive-pair weights. Its features and results were not used as inputs.
