Top 5% 1–80 Hz partial correlation links between retained shafts had lower mean replacement after one shaft omission than file change in 35 SEEG patients
We tested how recorded electrode coverage changes a conditional SEEG network. We used public interictal data from OpenNeuro ds004100, version 1.1.3. This new analysis reuses a published covariance package. It is not an independent replication. We omitted each named shaft and tested links between the remaining shafts. Both endpoint signals stayed fixed. The main score was full partial correlation at 1–80 Hz. The result used 35 patients, two 60-second files per patient, and 450 shaft omissions. Mean replacement of the strongest 5% was 6.7% after omission and 31.5% between files. The paired difference was −24.8 percentage points. Its patient bootstrap interval was −28.7 to −20.9 points. The difference was negative in 34 patients. Marginal scores stayed unchanged. Population controls, direct matrix checks, a full repeat, and four raw-file rebuilds passed. Deletion changes the statistical target. Stability does not prove neural accuracy. Code, primary edge scores, source metadata, hashes, and retrieval recipes are preserved.

Used its conditioning-set framework and independent-contact population control to define a distinct shaft omission test. This study removes a third named shaft and compares its effect with file change. It does not apply the earlier pair-specific endpoint exclusion rule.

Used all 72 preserved contact covariance files, source sidecars, pinned raw range records, and original retrieval and extraction code. The new study reuses the same cohort. It tests shaft omission against file change on matched retained links.

This study adapts the matched candidate-link comparison of omission with file change and the equal patient weights. The new test uses individual contact choice in two reference systems.
