Selected beta phase signs gave positive scores in the next minute after adjacent contact subtraction in all 19 tested SEEG patients
We tested beta phase sign persistence across two adjacent minutes in 19 public SEEG records from OpenNeuro ds003876 version 1.0.2. We subtracted adjacent contacts and used edges between different named shafts. Each edge had four distinct source contacts. Each shaft pair had equal weight within its patient. We selected edges in minute A and fixed their signs before scoring minute B. All 19 patient scores were positive. The mean was 0.02766, with a descriptive 95 percent patient bootstrap interval of 0.00961 to 0.05241. The median was 0.00843. Mean sign agreement was 54.90 percent. Mean selected-edge Dice overlap was 0.2121. The result shows a small persistent phase-sign component under this montage. It does not establish a neural cause or a clinical marker. This is an informed extension of an existing sample, not an independent sample replication. We rebuilt all 4,222,800 Fourier values from pinned public source ranges. They matched the archived inputs exactly. The package contains code, compact data, source provenance, results, figures, checks, and reproduction instructions.

Its beta graph result on reference choice informed the question. The original beta Fourier inputs and their provenance reached this study through the direct input publication. We did not reuse its saved graphs as new results.

We used all 19 Fourier inputs, three raw examples, source provenance, and the metadata and raw check code. Its contact-level signed result informed the new question. We tested a new adjacent contact montage with equal shaft pair weights on the same sample.

The inherited record selection and EDF reader originated in this work. We used the reader to rebuild the pinned public source ranges. We did not use its high gamma results as analysis inputs.

- usesHigher moments reduced conservative beta SEEG cutoffs under independent uniform segment phases in 19 records
The cohort selection and Fourier processing came through this work in the direct input publication. The present method keeps that selection and tests the same two minutes. It does not use selected phase-sign outcome values.
- usesMean rejection was 0.059 percent at a five percent level for 30-segment pooled beta SEEG tests under uniform segment phase rotations in 19 records
This publication supplied the 19 Fourier archives, cohort selection audit, public source metadata, raw fixtures, byte-range recipes, and inherited EDF reader. These inputs enabled the new conditional phase calibration test. All coefficients were rebuilt from pinned public source ranges. Its outcome values and selected phase signs were not used.

This archive supplied the fixed 19-record cohort, channel maps, source metadata, and pinned raw byte-range recipes. Its beta result was read before the local plan. All new high-gamma values came from fresh source bytes.

[Legacy relation: reproduces] We rebuilt all 19 inherited beta Fourier arrays from pinned public EDF ranges. All 4,222,800 complex64 coefficients matched exactly. This relation concerns the data extraction, not all results of that publication.

- usesOne beta sign per link gave higher mean test scores than frequency signs in 19 SEEG records
This publication supplied the 19 Fourier input files, fixed source recipes, and montage, coherency, and selection code. The new study compares two sign rules on the same records. It does not add an independent cohort.

This work supplied the 19 unchanged Fourier inputs, raw examples, source receipts, and contact-order rule. We adapted its retrieval, audit, and repeat scripts. We copied its raw validation script and EDF helper with credit. The new result tests phase-slope signs in the same patients. It is not an independent cohort replication.
