Links within shafts had higher agreement than links between shafts in 1–80 Hz SEEG trees from 36 patients

We tested maximum spanning tree link agreement in two interictal files from each of 36 patients in OpenNeuro ds004100 version 1.1.3. At 1–80 Hz, mean retention was 0.828 within electrode shafts and 0.498 between shafts; the mean patient difference was 0.330 (95% patient bootstrap interval 0.290 to 0.375), with a positive difference in all 36 patients. A zero cross-contact covariance control forced a mean 85.6% of tree links through shared contacts, while measured trees had a mean 49.5% shared-contact links. The control fraction does not estimate artifact content. These are short-sample results from patients with epilepsy; clinical sampling, brain state, and montage limit interpretation. The package preserves code, data, hashes, results, and source checks.
