Random disjoint 30-second SEEG power samples at 80 to 150 Hz, with 118 to 122 Hz removed, gave greater rank agreement within files than across files in 34 patients

We tested whether disjoint samples from one file give the same power rank agreement as samples from two files. We used public OpenNeuro ds004100 version 1.1.3. The selected sample had 34 patients and 3,325 bipolar SEEG pairs. Each map used 30 one-second windows and mean 80 to 150 Hz power, with 118 to 122 Hz removed. The same four maps entered both comparison rules. Mean Spearman agreement was 0.9869 within files and 0.9482 across files. The mean difference was 0.0387, with a 95 percent patient bootstrap interval of 0.0265 to 0.0523. The difference was positive in 32 of 34 patients. All six fixed sensitivity checks had positive mean differences. All source power inputs matched a fresh pinned rebuild. The repeat reproduced all 12 numerical files. The package preserves code, features, split and bootstrap tables, raw source records, and instructions. This is an informed extension in a reused clinical cohort. It measures map agreement and does not show clinical benefit. Source coordinate units conflict with the inherited distance field. Physical pair distances were not verified.

    This study supplied context for within-seizure and across-seizure rank agreement and the effect of temporal splits. Its score used baseline power change and unequal map durations. We test absolute interictal power with the same four maps and equal 30-second sample duration.

    This work supplied the unchanged 34-patient cohort, all 68 window-power files, source records, extraction code, and exact sign-count method. We checked the copied files and rebuilt the powers from the pinned public source. The new result compares four disjoint 30-second maps within and across files.

    This study supplied context for sample duration and across-file clinical label AUC change in the same cohort. We keep map duration fixed at 30 seconds and use power rank agreement as the primary outcome. Clinical label AUC change is a secondary descriptive outcome.

    This study supplied context for shared test epochs and top-contact agreement in a separate dataset. Our within-file maps have no shared selected window. The current file difference can occur without that direct window reuse.

    This study supplied related context for a four-map comparison and shared baseline effects. Our absolute interictal scores have no baseline estimate. We use the same four disjoint maps in both comparison rules.

    This work supplied the source EDF decoder and pair-selection code through the input archive. We preserved the original files. The added unit audit found a conflict between the distance_mm field and the source coordinate units. We report the literal raw-distance rule and do not claim a verified physical distance limit.
