Two nearby donors reduced withheld SEEG slope error by 25.1% across files in 20 ds004100 patients. Fits used 20–100 Hz and omitted 55–65 Hz.
This study tested a fixed donor method on public OpenNeuro ds004100 data. It excluded all patient IDs in the earlier ds005624 study. The main test used 1,140 target pairs on 228 shafts in 20 eligible patients. Two nearby, disjoint pairs predicted a target slope in a separate interictal file. Both main predictors excluded the source target slope. Fits used 20–100 Hz and omitted 55–65 Hz. Mean squared error fell from 0.823672 to 0.616531 against a shaft mean. The group reduction was 25.1%. The patient-bootstrap 95% interval was 18.9% to 31.4%. This interval assumes independent, exchangeable patients. All 20 patients had lower error. Four fixed checks gave the same direction. The data come from one hospital. The true time gap and recording overlap are not established. This result concerns a descriptive spectral feature, not a clinical decision. The package preserves exact inputs, a public retrieval recipe, source checks, code, all predictions, and bootstrap draws.

This earlier ds004100 study supplied the comparison task with local pooling of an observed target spectrum. The current task instead withholds the source target slope from both main predictors.

This work supplied the exact mean spectra and the frozen public source records. It also supplied licensed EDF decoding code and inherited timing and overlap audits. Fresh public downloads reproduced all 46 candidate spectra.
