20 ms HFO coincidence removal between shafts gave no clear SOZ rank gain in the first hour of 18 SEEG sleep records

We tested a fixed 20 ms rule in the first hour of 18 public SEEG sleep records. We removed each STE event with an onset on another named electrode shaft within 20 ms. Mean patient AUC was 0.7188 before removal and 0.7178 after removal. The mean change was -0.0010; its 95% patient bootstrap interval was [-0.0426, +0.0278]. Removal discarded 34.2% of the STE event marks. These data did not show a clear SOZ rank gain. Eleven patients gained AUC, five lost AUC, and two had equal AUC. In the largest-loss case, removal discarded all 14 STE events from the two SOZ channels. Fixed time-limit, detector, and time-window checks also gave uncertain mean changes. The test uses released event marks and clinical labels. It does not estimate surgical benefit. The package contains source archives, hashes, event witness links, code, figures, and full patient results. Separate source parsing and timing checks passed. All 16 numerical files matched an offline repeat.

This publication supplied the pinned ds005398 source archives, manifest, source parser, and AUC functions. We used them to test a new rule that removes same-detector events with a nearby onset on another shaft.

usesDuration weighting changed STE channel lists without a clear SOZ rank gain in 18 SEEG sleep records
The package supplied the exact source archives, pinned manifest, and public retrieval code. These inputs supported a new count and duration comparison.
usesEqual minute STE weights gave a SOZ rank gain interval that included zero in the first hour of 18 SEEG sleep records under independent, exchangeable patient sampling
This publication supplied the original pinned public retrieval recipe and code license. We retained its retrieval code and source version records.
usesMedian HFO duration gave no clear STE SOZ ranking gain beyond count and contact number in 18 SEEG sleep records
This work supplied the compressed source event files, metadata, EDF headers, pinned retrieval manifest, retrieval code, and channel and repeat rules. Fresh public bytes were checked before the new duration analysis.
usesThe 95 percent patient interval for mean STE AUC within shafts was above 0.5 in the first hour of 17 SEEG sleep records under independent, exchangeable patient sampling
Read its conventional STE and MNI count results before the local plan. That same-cohort knowledge informed selection of STE for the primary local test. No prior code or numerical result was used to calculate our local AUCs.
