Time concentration of 80–150 Hz SEEG power gave a mean within-shaft AUC of 0.720 for seizure-onset pairs in 30 patients with two 60 s clips each
We tested whether time concentration of 80–150 Hz bipolar SEEG power ranks clinical seizure-onset pairs above other pairs on the same named electrode shaft. We used public OpenNeuro ds004100 version 1.1.3 and two 60 s interictal clips per patient. The score was the fraction of power in the six largest one-second windows. Thirty patients had both pair labels on a shaft. They supplied 196 eligible positive pairs and 341 same-shaft negative pairs. Mean within-shaft AUC was 0.720, with a 95 percent patient bootstrap interval of [0.658, 0.783]. Twenty-seven patient AUC values were above 0.5 and three were below 0.5. Mean power gave a higher mean local AUC of 0.830. Whole-implant concentration AUC was 0.707 with the same positive pairs. The interval for within minus whole included zero. All five fixed sensitivity checks had mean concentration AUC above 0.5. We downloaded all 72 pinned source ranges again. All 68 rebuilt power files matched the earlier arrays exactly. The package preserves code, source metadata, powers, patient results, checks, and reproduction commands. This is a local comparison in previously studied patients. It does not establish accuracy in new patients or a treatment rule.

This work supplies the fixed concentration measure, cohort selection, archived power arrays, source metadata, pinned byte-range recipes, and extraction code. We rebuilt all inputs and added same-shaft comparisons with the same eligible positive pairs in each contrast.

The title helped identify a within-shaft control question. We read the full report after the main result. We use it as related method context. Its local-reference mean-power score and selected cases differ from the present concentration test. No code or data files were reused.
