Models with fixed contact magnitudes and independent uniform phases gave 77.77 percent mean retention of the strongest quarter of shared bipolar beta edges across two runs from 16 SEEG patients

Two public interictal SEEG runs from each of 16 selected patients supplied fixed contact Fourier magnitudes at 13–30 Hz. Independent uniform contact phases gave 77.77 percent mean retention of the top quarter of shared-contact bipolar edges across runs. Independent uniform edge selections gave a 25.53 percent reference. Random assignment of run 02 contact magnitude profiles gave 25.47 percent retention. Shared contacts and stable assigned magnitude profiles can make strong phase edges repeat when contact phases are independent. The package has features from both runs, 499 graph draws per model, exact expectations, source checks, code, and retrieval instructions. The result applies to this selected cohort and phase model. It does not show that any recorded neural connection is false.
