Signed imaginary beta coherency residuals showed positive mean agreement in 36 patients' paired 60 s SEEG samples with fixed polarity

We tested signed SEEG map agreement in 36 patients with two public interictal files each. Each sample was 60 s. We removed additive endpoint patterns within each pair of named shafts. The mean beta residual cosine was 0.231. The 95% patient bootstrap interval was 0.185 to 0.280. Fixed half-strength transfer had a mean relative error reduction of -2.1%. Its 95% patient interval was -6.6% to 2.6%. This interval included zero. The package contains all signed maps, patient results, code, source hashes, and a raw-data retrieval recipe. The result uses fixed bipolar polarity and a selected epilepsy cohort. The file time gap and partial source overlap are unknown. The result does not establish causal signal flow.

    We reused the pinned source manifests, sidecars, raw-range download code, and metadata checks. Its endpoint method motivated the residual control.

    We reused the checked EDF selection and Fourier code. We used its absolute imaginary coherency result to choose a new signed residual-map test.

    We used the original paired SEEG cohort and public EDF retrieval record through the later pinned manifest. We checked the cohort against the full source tree.
