Spearman gave higher agreement than Pearson between 1–80 Hz bipolar SEEG maps in 18 patients and lower agreement in 18 patients
We tested whether sample ranks improved the order of SEEG link strengths between two files. We used two 60-second excerpts from each of 36 patients in public OpenNeuro ds004100, version 1.1.3. The primary test used 1–80 Hz bipolar channels that shared no contacts. It scored only links between different electrode shafts. Mean agreement of absolute link order was 0.43208 with Pearson correlation and 0.44655 with Spearman correlation. The mean paired difference was +0.01447. Its 95% patient bootstrap interval was [-0.00152, +0.03947]. The difference was positive in 18 patients and negative in 18 patients. The median difference was +0.00049. The primary interval included zero. A mean gain under the patient sampling model is uncertain. The package preserves all source pins, signed link maps, patient results, code, and checks. This test measures agreement in the selected files. It does not establish the accuracy of neural connections or predict clinical outcomes.

This work supplied the fixed clipping threshold of three robust scale units for a comparator. The present study uses the same cohort. It tests agreement between files with channels that share no contacts. It does not repeat the prior calibrated prediction endpoint or provide an independent cohort test.

This work supplied the pinned source ranges, BIDS metadata, contact selection, EDF parser, and covariance audit values. We retrieved the raw ranges again. We used the raw signals to compute new Spearman, Pearson, and clipped Pearson link maps.

We used the fixed 36-patient selection, public byte-range hashes, extraction functions, raw fixture, and fixed rank and clipped comparison maps. We tested an established sign method against a common Pearson target and audited Pearson map values.
- usesMean 1–80 Hz SEEG link flag rates were higher between files than within files in 36 patients
This study supplied contact selection, source pins, metadata, and layout code. We used longer raw ranges and new block scores.
- usesThe 95% interval included zero forecast gain from half of early 1–80 Hz SEEG link change in 36 patients, assuming independent, exchangeable patient sampling
We retained its contact selection and contact-disjoint bipolar layout through the source map package. These rules fixed the 36 patient layouts before the new forecast scores were calculated.

The copied source package uses this work for contact selection, layout code, metadata, and source pins. We preserved these files and their license.

We used the 72 signed Pearson map arrays, the fixed patient cohort, contact selection, and public source records. We copied the Pearson arrays without change. We tested a new link selection rule and agreement endpoint on this same cohort.

Used signed Pearson maps, disjoint bipolar channel definitions, the raw fixture, and EDF reconstruction code. The new test measures hub changes after one shaft is omitted.
