Five late SEEG bins had lower mean accuracy than one window at equal value and pair counts in eight STReEF patients

We tested whether short late windows improve stimulation site reading when early SEEG inputs are unavailable. The public source was STReEF, OpenNeuro ds005448, version 1.0.0. Eight selected patients supplied four conditions each. Five pulses per condition fit each reader. Five later pulses with reversed recorded contact order tested it. Five short windows supplied eight cosine values each. One long window supplied 40. Both used the same samples strictly between 100 and 500 ms and four selected recording pairs. Mean accuracy was 40.0% for five windows and 47.5% for one. The mean difference was -7.5 percentage points. The patient bootstrap 95% interval was -20.0 to +3.125 points. The exact sign-flip p value was 0.359375. This reference assumes independent patients and sign-symmetric effects under the null. These data did not establish a population loss or gain. The inherited late eight-value reader gave 58.125%. More late values did not help this fixed reader. All 19 fixed cases are retained. Independent calculations reproduced all 3,040 predictions. A second download reproduced all source features. Three figures, source receipts, features, fitted readers, code, and replay instructions are preserved. This is an offline input exclusion test in a reused clinical sample. The split is not globally chronological. Residual artifact and time drift can carry site information. No online performance or neural mechanism is established.

    This study uses the metadata selection rule and source retrieval basis. The package preserves exact source ranges, versions, hashes, and the inherited implementation.

    This study uses the fixed eight-patient sample, 320 pinned source epochs, and five-pulse reader. It reproduces all patient scores for the three inherited eight-value controls.

    This study uses the distinct-pattern pair selector, pooled noise scale, and nearest-mean reader to compare two late feature sets at equal counts.
