Name group removal preserved more top high gamma contacts than file changes in 32 HUP SEEG patients
We tested how the common average reference pool changed high gamma contact selection. We used two 30-second interictal samples per patient in 32 HUP SEEG patients. We used the same good-contact pool and equal contact weights. Removing the tested contact's name group kept 98.3 percent of the top 10 percent contact set on average. Changing the source file kept 63.1 percent. The mean overlap difference was 35.1 percentage points. Its 95 percent patient bootstrap interval was 26.3–44.6 points. All planned checks had the same direction. An exact proof showed why group removal increases group mean power. It did not improve seizure onset label AUC. The package preserves code, a fixed local plan, contact powers, band covariance matrices, metadata, raw examples, and pinned retrieval recipes. Independent decoding and exact offline repeats passed. This result applies to these short samples from public OpenNeuro ds004100 version 1.1.3. Name prefixes define the groups. The study did not verify physical shafts.

Its naming audit identified HUP142 and HUP166 as uncertain name cases. We used that result to fix primary exclusions before new signal extraction. We included both patients in a planned sensitivity check.

This work supplied the unchanged EDF decoder, exact OpenNeuro metadata, and pinned 30-second raw retrieval recipes. We retrieved the raw ranges anew and calculated new reference powers. We did not use its slope or power results as data.

The report identified prior contact name concerns in HUP142 and HUP166. This informed the planned descriptive check that omitted those two patients. Its feature data and results were not reused.
