Two 60-second SEEG clips gave no clear evidence of greater excess 80 to 150 Hz power change at seizure onset pairs in 30 patients

This study tested whether seizure onset pairs have greater excess power change between files than other pairs in the same contact name groups. It used public SEEG data from OpenNeuro ds004100 version 1.1.3. The primary analysis used two 60-second clips per patient and 80 to 150 Hz power. Excess was absolute change between files minus absolute change within files. The analysis gave groups equal weight within patients and patients equal weight in the cohort. There were 30 patients, 69 groups, 196 onset pairs, and 341 other pairs. The mean onset minus other contrast was -0.088 dB. The 95 percent patient bootstrap interval was -0.415 to 0.218 dB. The exact two-sided patient sign flip test gave p = 0.610. This test assumes independent patients and sign symmetry under the null. The result gives no clear evidence of greater excess at onset pairs. It does not establish equal change. The fifth-minute estimate was -0.093 dB in the same patients. Fresh source downloads gave byte-identical copies of all 136 feature archives. Separate calculations checked source metadata, two raw examples, all endpoints, and bootstrap results. The package preserves source code, input powers, patient and group results, source identities, figures, and reproduction instructions. Contact name groups are not verified brain regions. The inherited coordinate cutoff has an unresolved physical unit issue. The result applies to selected short clips and this power measure.

    This study uses the contact name group comparison as design context. It tests a change measure within those groups rather than power discrimination.

    This study uses the first-minute power arrays, source metadata, retrieval records, and unchanged extraction code. They supply the primary inputs. All reused file hashes and fresh source outputs were checked.

    This study uses the fifth-minute power arrays and unchanged extraction code. They supply the second time interval in the same patients. All reused file hashes and fresh source outputs were checked.

    This study uses the overall between-file and within-file comparison as design context. It adds a clinical label contrast. It also retains the limit that temporal dependence can affect excess change.

    This package corrects the integrity check. The first check rejected generated download metadata outside the file manifest. All six numerical result files, input powers, source records, and the fixed protocol are unchanged.
