Under patient independence, the mean 6 dB rise time order score interval included zero within SOZ classes in 19 SEEG patients with two seizures each
We tested repeat fast-to-slow power rise time order in public ds004100 SEEG data. The fixed rule required a 6 dB rise in two successive one-second blocks. Each seizure used its own baseline. We compared jointly detected bipolar pairs within the same shaft and the same pure clinical seizure onset zone (SOZ) label class. The primary set had 19 selected patients, two seizures each, and 714 bipolar pairs. The mean Kendall tau-a was 0.0148. The patient bootstrap 95% interval was [-0.1638, 0.1633]. The sign reversal p value was 0.86834 under independent patients and null sign symmetry. This result does not establish absence of repeat order. A later exact split showed that an all-pair score of 0.1084 included detection-status order contributions of 0.0742. The 9 dB check was higher but used a different sample. This is an exploratory secondary study of a previously selected cohort. Fresh public signal retrieval reproduced all 658,080 source power values exactly. The package preserves code, input arrays, pinned source recipes, results, proofs, figures, and repeat instructions.

We used its 26-patient feature arrays, public source pins, metadata, headers, and extraction code. These files enabled the new within-label time order test. Fresh public signal sections reproduced its archived power values exactly.

This earlier study tested thresholded rise time order. It informed the distinction between magnitude order and timing order in the report.
