Chance correction under uniform one-second phase shifts gave an uncertain SOZ rank gain for 20 ms detector agreement in the first hour of 18 SEEG sleep records
We tested whether local chance correction improves seizure onset zone (SOZ) channel ranks from detector agreement. We used the first hour of 18 public SEEG sleep records in OpenNeuro ds005398 v1.1.3. The sample had 1,285 eligible channels. An STE start had support from an MNI start within 20 ms in the same one-second bin. The chance model shifted the local MNI pattern by a common uniform phase. We proved and checked its exact expected support count. The adjusted score was observed support minus this expectation. Mean patient AUC changed from 0.6906 to 0.6960. The paired mean gain was 0.00537. Its 95% patient bootstrap interval was -0.00631 to 0.01577. The exact primary sign flip p value was 0.3711 under independent patients and null sign symmetry. Thus, the data did not establish a rank benefit at this setting. This study reuses patients from prior work. It tests source labels, not clinical benefit. The package contains source event data, pinned provenance, the method proof, code, results, figures, and repeat instructions. All 94 fresh source checks matched. The full analysis reproduced the saved numerical files byte for byte.

We used the preserved source event bytes, metadata, EDF headers, manifest, source parser functions, and pinned retrieval script. The prior detector matching result informed the question. We computed new support and chance correction scores. We reused this patient cohort.

The prior comparison of STE and MNI channel maps informed the question about local chance correction. We did not use its calculated maps or its 17-patient selection rule.
