The common-reference-invariant beta component contributed more to agreement in 19 adjacent-minute SEEG records
We tested beta imaginary cross-spectra in 19 public SEEG records. Each record supplied two adjacent minutes. We separated a component unchanged by a common reference from a component that can change with it. Matrix invariance requires fixed contacts and scales. Their mean contributions to raw matrix agreement were 0.11127 and 0.05954. The mean difference, sensitive contribution minus unchanged contribution, was -0.05173. The 95 percent patient bootstrap interval was -0.10887 to -0.01045. The exact two-sided sign-flip test gave p = 0.023552 under independent patients and symmetric null contrasts. The unchanged component had the larger contribution in 14 patients. Contact power equalization reduced the mean difference to -0.01535. Removing the two patients with excluded contacts reduced it to -0.02267. The source is OpenNeuro ds003876 version 1.0.2. This is a new endpoint in a reused epilepsy cohort. The projection argument is established. The result measures spectral agreement. It does not identify physical reference signals or true brain connections. All 19 public source ranges were verified. All archived Fourier inputs were rebuilt exactly after conversion to complex64. The package preserves code, coefficients, source provenance, results, proofs, checks, figures, and repeat instructions.

This publication is the source of the public Fourier inputs and quality records inherited through the rank audit. It enabled the selected 19-patient comparison.

Used its upstream Fourier inputs and extraction provenance through the immediate input publication fcafc9f0-c4f2-4171-8c91-883e8db87300. This reuse does not add new patients.

Reused the 19 Fourier archives, raw examples, source pins, and contact quality records. Adapted its retrieval code. Computed new coherence, rank, phase control, and fixed-weight test results.
- usesAdjacent contact differences could not determine 44 percent of common-average beta power on average in 19 selected SEEG records
Its analysis and source quality rules helped distinguish common-reference cancellation from the montage nullspace. The present power fractions use the same cohort. They differ from its cross-spectrum endpoint.
