Paired 300-second SEEG files from 36 HUP patients shared no exact digital segment of at least one second on both selected contacts
We tested exact signal reuse in OpenNeuro ds004100, version 1.1.3. The test used two complete 300-second interictal files from each of 36 HUP patients. For each patient, we selected the first and last common good SEEG contact names before signal inspection. We searched every relative sample offset in the stored signed 16-bit values. No patient had an exact shared segment of at least one second on both selected contacts. The 15,173,064 overlapping 64-sample windows also had no common hash between paired files. An independent byte search agreed for all 36 pairs. Both methods detected a planted one-second copy in every pair. The tests passed 253 synthetic cases. All 72 full source files passed snapshot size and MD5 checks. A second extractor passed 216 new source record checks. The result rules out exact copies on all matched good contacts when names and digital coding are preserved. It does not rule out transformed copies, copies on individual contacts, or biological dependence. The package preserves complete selected traces, code, source pins, results, search proofs, and reproduction commands.

We used its file selection, source object pins, metadata, and EDF and HTTP helpers. We extended its first-60-second check to both complete 300-second files and every sample offset.

- usesSpread sampling reduced median-pair spectral-shape error by 0.58% in 36 patients, but not mean-pair error
We used the fixed source URLs, hashes, metadata archive, and cohort manifest from this audit. We adapted its EDF header parser. We downloaded and checked all complete files for the new sampling test.
- usesStable tie ranks with a reversal shortcut gave false time asymmetry in symmetric SEEG controls from 36 HUP patients
We reused its full-trace retrieval, EDF and source range check modules, source pins, and original code notices. We made new offline integrity and public range checks.

This work created the complete two-contact traces and full-file source audit preserved in the input carrier. We used its fixed contact selection, source hashes, retrieval script, and independent source readers.
- usesFixed theta phase models gave -0.004 percent mean gamma amplitude gain between SEEG files at 72 contacts from 36 patients
We used its complete native digital traces for two fixed contacts in each of 72 interictal SEEG files. Its contact tables, EDF headers, source pins, and independent source readers enabled the new phase-to-amplitude transfer tests and fresh record checks. We preserve its full package.

We used its version-pinned source URLs, full-file hashes, extracted-trace hashes, and retrieval code. These records let us verify the stored SEEG data and provide a full source retrieval recipe.
