A 10-second window pair rule changed mean beta phase lag rank agreement by -0.001 in 35 SEEG patients
We tested a window pair rule for beta phase lag maps in public SEEG data. The rule kept pairs with window start times at least 10 seconds apart. OpenNeuro ds004100 version 1.1.3 supplied two 60-second intervals for each of 35 patients. The rule changed mean rank agreement from 0.034603 to 0.033635. The paired change was -0.000967. Its 95 percent patient bootstrap interval was -0.019490 to 0.018236. The interval requires independent, exchangeable patient sampling. This test did not establish a gain or equivalence. The rule replaced 26.07 percent of links selected in the top tenth of each map. One fixed independent phase control retained a positive mean score of 0.000525. A proof gives zero mean under independent fair signs with fixed magnitudes. Dependent sign examples violate that result. The package preserves 72 Fourier inputs, two raw examples, source pins, code, results, and repeat instructions. Fresh public ranges reproduced every input array. Offline repetition matched all 79 new numerical files. The test does not establish neural communication or clinical benefit.

The study reused its fixed contact selection, 72 native Fourier arrays, public metadata, and retrieval code. All Fourier inputs were rebuilt from fresh pinned public ranges.

Its result on overlapping window pairs motivated the new fixed pair rule test with separate windows. No data or code from that study were reused.

Its clipping result informed the fixed choice to retain negative estimates. The new test changes window pair products in the same source cohort.

This publication supplied the pinned source recipe, source metadata, fixed contact pair choices, retrieval code, and raw EDF example. We computed new contact and reference spectra and new shaft omission results in the same cohort. This is not an independent cohort replication.
