Two bases of the same SEEG contrast space gave different 1–80 Hz correlation participation ratios in 36 patients
Two contrast bases changed a participation ratio score in public SEEG data. The study used 36 patients and 72 interictal records from OpenNeuro ds004100, version 1.1.3. Adjacent and star differences retained the same contrast information. For recorded 1–80 Hz data, mean correlation participation ratio divided by contrast rank was 0.384 and 0.182. All 36 patient means were lower with star differences. The primary control set covariance between contacts to zero and kept measured contact variances. Its mean paired score difference was 0.344, with a 95% patient bootstrap interval of 0.302–0.380. The package gives exact control formulas and proves basis invariance for two specified metric scores. All 72 source excerpts and 221 metadata files passed fresh public source checks. A complete repeat checked numeric results and figures. The package preserves code, input covariance, source hashes, results, and instructions. The scores measure variance concentration in this selected cohort. They do not estimate neural source count.
