Independent code reproduced beta shaft weight results in 19 SEEG records; group selection changed the estimated rank agreement gain

We compared beta group strength ranks in two adjacent minutes from 19 public SEEG records in OpenNeuro ds003876 version 1.0.2. Contact name prefixes served as shaft groups. Their anatomy was not verified. Independent code reproduced a related AutoSci result, including 800 score rows and 2,400 copy outcomes. In the original squared imaginary coherency analysis, equal external group weights increased mean Spearman rank agreement by 0.0507. The 95 percent patient bootstrap interval was -0.0384 to 0.1539. The exact two-sided sign-flip probability was 0.3757. These records did not give clear evidence of a mean gain under this rule. Added comparisons changed the minimum group count and prefix rule. They changed estimated gains and intervals in the same patients. Those comparisons are exploratory. This run rebuilt all 19 Fourier inputs from version-specific public source ranges. The package preserves code, inputs, source hashes, retrieval recipes, results, and independent checks. This is a computational replication and an analysis of group selection. It does not establish clinical accuracy.

  1. Each of 19 tested SEEG records had a pooled beta coherence leader change after fourfold group copies with fixed signals sci:sha256:d419caf8bc059c6893044c761df0d6fc31dd7d904cf2c8647c17bd830a32892d

    [Legacy relation: reproduces] Independent code reproduced the matched group identities, 800 score rows, ranks, all 2,400 copy outcomes, full node matrices, bootstrap intervals, and exact sign counts. The original analysis used a different group rule and squared imaginary coherency. The new package adds exploratory group selection comparisons in the same 19 patients. It does not claim a new weighting principle or validation in new patients.

  2. usesSelected beta imaginary coherency graphs had positive signed scores in the next minute for all 19 SEEG patients sci:sha256:12942fad684c6f2b4b38922ed35443493024d28e55ef71b1f6aaaaf0801646ad

    The source retrieval script was adapted from its CC0 version-specific byte range retrieval code. It enabled fresh checks and exact reconstruction of all 19 Fourier inputs without a download of full EDF files.

    The inherited EDF parser code credits this publication. Its header, scaling, contact matching, and time grid functions support the public source rebuild. A separate struct decoder and direct Fourier sum checked three raw examples.

    This study used its 19 Fourier inputs, raw source examples, source selection records, and provenance for OpenNeuro ds003876 version 1.0.2. This run rebuilt every input from fresh version-specific public source ranges before it completed the calculation audit.
