201 trials with Artifact=0 contained SEEG endpoint runs of at least 1 ms in ds004752 version 1.0.1
We checked stored integer limits in public stereoelectroencephalography (SEEG). The source was OpenNeuro ds004752 version 1.0.1. We checked all 68 released iEEG EDF files. The files covered all 15 patients and all 3,353 released eight-second trials. A trial was positive when any source SEEG contact had a run at -32768 or +32767 for at least 1 ms. Duration was sample count divided by sample rate. A sign change or trial boundary ended a run. Among 3,185 trials with source Artifact=0, 201 were positive (6.311 percent). These trials came from 5 patients. sub-12 supplied 196 of the 201 unflagged positive trials. Among 168 trials with Artifact=1, 1 trial was positive. At 5 ms, 194 unflagged trials were positive. The source flag does not guarantee the absence of these stored runs. The runs do not establish acquisition clipping or its cause. All full source hashes passed. A separate reader checked raw examples from fresh pinned source ranges. All result tables repeated exactly. The package contains code, source versions, metadata, full counts, raw examples, figures, and retrieval instructions. This is a new census of a previously studied patient group.

This work supplied the pinned source manifest, source metadata, and the known endpoint finding in patient 12. We checked every source file again and added a census across all 68 released files and all SEEG contacts.

- usesRemoving trials with hippocampal endpoint runs of at least 1 ms changed the mean 8 minus 4 letter theta contrast by 0.002 dB in 14 ds004752 v1.0.1 patients under the stated windows and linear model
This publication supplied the all-contact endpoint run census for all 68 source files, source headers, complete source hashes, and census code. We used the run positions to define and test the new hippocampal window screens. Fresh complete checks of all six affected patient files matched the run lists and screen flags.
- usesA 1 ms endpoint screen changed common-average theta power on unmarked hippocampal contacts in 89 ds004752 v1.0.1 trials
We use its complete endpoint run tables, source headers, metadata, fixed source versions, and full-file hash evidence. They define the window screens and retrieval recipe. Every retrieved parent file passed its archived size and hash checks.
- usesA 1 ms endpoint screen changed the fitted hippocampal theta phase contrast by 0.089 dB in 14 ds004752 v1.0.1 patients
We used its complete endpoint runs, trial tables, contact-trial tables, EDF headers, pinned source records, and census code. They enabled the exact task-window masks for all 3,353 source trials. We preserved their hashes and independently checked selected raw windows and one full session.
- usesUnder patient independence and null sign symmetry, tests did not detect phase or load changes in 2–30 Hz hippocampal geometric mean profile entropy in 14 first SEEG sessions with stored reference
Its full release endpoint run counts show why Artifact=0 cannot ensure clean stored signal. We cite this limit and do not use its trial labels for exclusion.
- usesChanging the preceding trial changed fixation theta power under a centered FIR filter in 14 SEEG patients
Its source integer endpoint census motivated the native quality check. This study used declared EDF endpoints on the selected hippocampal contacts. It did not repeat the full contact census.
- usesA 1 ms hippocampal endpoint screen changed the mean late theta load coefficient by -0.00324 dB in 14 ds004752 patients
This archive supplied the same-sign SEEG integer endpoint run census, source metadata, EDF headers, and pinned raw file hashes. We joined each run to the theta trials and checked all six affected-patient raw files.
- usesShared fixation baseline subtraction gave higher hippocampal theta correlations between encoding and maintenance than linear baseline control in 14 SEEG patients
Its stored integer endpoint census motivated the fixed check that omits patient 12. We do not treat endpoint runs as proof of amplifier clipping.
- usesA 1 ms endpoint screen changed the mean raw theta contrast more than theta excess in 14 ds004752 v1.0.1 patients
This publication supplied complete integer endpoint run tables, EDF headers, source object versions, and source hashes. These inputs enabled exact window masks. We checked its complete archive and freshly rebuilt nine complete recordings, including all six patient 12 sessions.
