Contact power improved shared-contact correlation predictions in phase-randomized SEEG from 12 patients
We tested a contact-power model with public interictal SEEG from 12 patients in OpenNeuro ds004100 version 1.1.3. Two bipolar channels shared a contact. Each patient supplied two 60-second windows. Independent phase changes removed cross-contact timing in the control signals. In the primary 1 to 45 Hz band, mean absolute prediction error was 0.0226 with contact power and 0.0573 with the fixed value of -0.5. The mean paired decrease was 0.0347 (95 percent participant bootstrap interval 0.0262 to 0.0420). The cohort size was reduced after the pilot because downloads were slow. The package preserves code, source range hashes, metadata, results, and a retrieval recipe. The model assumes zero cross-contact covariance. It is a pipeline diagnostic. It is not a correction for observed brain connections.

This study uses the fixed 12-patient cohort, source metadata, pinned S3 versions, range hashes, and an adapted EDF reader. All Fourier inputs and numerical results were built again from raw source ranges. Prior analysis arrays and numerical results were not used.
