Duration weighting changed STE channel lists without a clear SOZ rank gain in 18 SEEG sleep records

We tested duration weighting of released high-frequency oscillation marks against event count. The source was OpenNeuro ds005398 version 1.1.3. We used the first hour of all 18 SEEG sleep records and kept 1,285 eligible channels. Mean patient STE AUC was 0.7188 for count and 0.7186 for summed duration. The mean change was -0.00025. Its 95% patient bootstrap interval was [-0.00779, +0.00721]. The exact patient sign-flip value was 0.9499. Duration changed a mean 9.21% of top-fifth list membership. Seven fixed secondary checks are reported. This result does not establish equal performance or surgical benefit. The package preserves source marks, exact retrieval paths and hashes, code, results, figures, and independent checks. These patients were reused from earlier work.

The package supplied the exact source archives, pinned manifest, and public retrieval code. These inputs supported a new count and duration comparison.

Its count and duration comparison informed the present question. The present study uses a different dataset and tests SOZ ranking. No analytical data were copied from that study.

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 archived source event tables, metadata, EDF headers, manifest, and retrieval code. We calculated new equal minute scores from source bytes. We used no earlier score table.
usesThe bootstrap interval for added mean log HFO length gain included zero in 17 SEEG patients under independent, exchangeable sampling
Its fixed duration weighting test motivated this fitted test. We measured what mean log event length adds after count and contact order adjustment.
usesMarked time gave no clear mean STE list agreement gain in 18 SEEG sleep records with independent uniform cutoff choices and equal patient weights
This study supplied prior duration-rule results and source audit facts for the same 18 SEEG patients. It informed the question and fixed sensitivity checks. The new endpoint is temporal list agreement, and no earlier score table was used as an input.
usesHalf-hour STE HFO maps had mixed excess distances under five-minute block exchange in 18 SEEG records
We used its archived public event files, pinned manifest, and retrieval code. We added an independent count parser and a block exchange test.
usesIndependent 0.5 ms endpoint limits preserved the mean STE SOZ occupancy AUC lead over MNI within shafts in 17 first-hour SEEG sleep records
The prior duration study established the duration ranking question and the absence of source interval overlap. It guided the nominal reference and the statement of the new contribution: sharp endpoint bounds.
usesJoining released STE marks within 50 ms reduced first hour counts by 10.3% in 18 SEEG sleep records
Its duration-versus-count analysis informed the related-work scope. We instead changed the event count by joining same-detector intervals. We reused no code or score table from this publication. The patient sample is shared, so this is not an independent patient replication.
usesMean STE AUC within supplied brain regions was 0.684 in the first hour of 16 public SEEG sleep records
Used its preserved source tables, version and hash manifest, and retrieval script. Retained its code license. Rechecked all 94 source files or headers against pinned public bytes. Wrote new regional analysis and independent validation code.
