Beta phase-slope threshold selection left sign agreement gain uncertain in 25 patients with two 60 second SEEG records. Intervals assumed independent, exchangeable patients.
We tested beta phase-slope threshold selection in paired 60 second SEEG records from 36 epilepsy patients. The public source was OpenNeuro ds004100 version 1.1.3. The rule abs(Z) > 1.96 gave 49 training selections from 47 unique links in 25 patients. Eleven patients had no selected link. Selected sign agreement averaged 61.33 percent with equal patient weights. Agreement for all links averaged 52.77 percent in the same patients. The mean gain was 8.56 percentage points. The 95 percent patient bootstrap interval was -7.02 to 23.39 points. It assumed independent, exchangeable eligible patients. The evidence left the mean gain uncertain. Fixed checks and a matched 30 second comparison also had limited population information. All 72 Fourier inputs matched a fresh rebuild from pinned public raw data. All 221 metadata files matched. An independent score calculation and a full offline repeat passed. A delayed common-source model also produced selected signs without direct interactions. The package preserves code, compact inputs, source recipes, contact lists, metadata, results, figures, bootstrap samples, and repeat instructions. This is secondary work on fixed brief records. It does not establish a neural error rate or a clinical effect.

This package supplied the 72 Fourier inputs, fixed contacts, metadata, and pinned raw retrieval recipe. Its earlier map result informed the new threshold question. All 72 inputs were rebuilt from fresh public requests.

The inherited retrieval and EDF voltage decoding methods came through publication 2928cfb3-eb71-42c6-afbd-f366d9a86ca2. We used these methods for the full raw input rebuild and preserved their licenses.

Background method reference for the phase-slope index; the publication states that its defined estimator uses different segmentation and is not a numerical replication of all methods in that paper.
