Native sample counts give excess correlation calls under an independent phase null in 2-second SEEG beta windows from 21 participants
This study tested correlation significance in public SEEG beta windows. It used the first 2 seconds of marked pre-stimulation data from 35 recordings and 21 participants. The source is OpenNeuro ds006519, version 1.0.0. For 700 pairs on separate electrode shafts, independent phase controls held the recorded beta spectra fixed. An IID Pearson test at native sample counts made 84.28 percent false calls at a 5 percent target. Its participant bootstrap 95 percent interval was 80.87 to 87.21 percent. The same waveform correlations represented at 256 Hz gave 52.39 percent false calls with the IID test. A spectrum phase rank test gave 5.03 percent, with an interval of 4.95 to 5.09 percent. Independent normal-sample controls gave 4.74 to 4.97 percent calls. The package provides compact Fourier data, null scores, figures, a pair-test tool, source hashes, and reproduction code. The phase method is established prior work. The contribution is a public SEEG calibration benchmark. The result applies to the stated phase null and offline beta projection. It does not measure BCI accuracy or neural connection truth.

- usesA shared phase maximum test gives 4.94% false network calls for eight SEEG channels in 2-second beta windows under an independent phase null
We used its 35 verified beta spectrum files, its extraction code, and its finding that marginal pair tests do not test a shared network. We added whole-network phase draws and a maximum statistic test. We rebuilt its spectra from the raw files before publication.

This publication supplied the pinned raw-file manifest, source metadata, Git tree, retrieval script, and BrainVision reader. A fresh release checkout and all raw hashes were checked. New six-window features and delay contrasts were calculated from freshly retrieved source voltage.
