Centered hippocampal SEEG spectra matched 9 of 12 patients across two task sessions with fixed contacts in ds004752
We tested patient matching with public hippocampal SEEG data from ds004752 version 1.0.1. We used fixed contacts in 12 patients and two task sessions. We removed constant power gain and gave three memory loads equal weight. A fixed spectrum rule matched 9 of 12 patients. The exact label assignment probability was 48/479001600 under conditional label exchangeability. Five planned checks gave 6 to 9 matches. Stable contact placement or other recording properties can explain the information. The result does not establish a biological identity signal or performance on new patients. The package preserves spectra, code, metadata, results, figures, raw retrieval recipes, and independent checks. Fresh raw checks cover one trial in each of 24 sessions.

We used its 24 spectrum files, raw examples, metadata, source range records, and three Python files. These files supplied fixed hippocampal SEEG measurements and versioned retrieval recipes. Our new analysis tested spectrum matching across sessions, with a different outcome and trial selection.
