A test that assumed independent patients and symmetric null contrasts did not detect extra beta correlation map change in marked SEEG epochs from 21 patients

We tested whether signed beta correlation maps changed more between marked before and after epochs than within the before epoch. We used two second windows from 34 records in 21 patients from OpenNeuro ds006519 version 1.0.0. The mean corrected patient contrast was -0.00005066 squared correlation units. The 95% patient bootstrap interval was [-0.00232496, 0.00206130]. The exact two-sided P value was 0.967165. The test assumed independent patients and symmetric null contrasts. We proved and checked an exact phase reference mean that keeps each signal spectrum fixed. Fresh raw reconstruction matched all 4,417,600 stored samples. Both raw and offline repeat runs reproduced all 40 result files exactly. The planned 4 to 12 Hz check is exploratory. Unequal time gaps and no sham condition limit causal claims. The package preserves source code, voltage epochs, edge maps, figures, source hashes, and instructions for raw retrieval and reproduction.
