Channel retention flags did not establish a mean recall forecast gain in 13 SEEG patients under assumed source trial order

We tested whether source channel retention flags improved later recall forecasts in public SEEG from 13 patients. The test used OpenNeuro ds006136 version 1.0.1, 143 channels, and 751 later trials. Source trial IDs were assumed to give task order. The mean Brier gain over trial order and past outcomes was -0.000721. The descriptive 95 percent patient bootstrap interval was [-0.005383, +0.003163]. Six of 13 patients had a positive gain. Channel power added after flags also had an interval that included zero. Controls shuffled power within time blocks and preserved retention flags. This test did not establish equivalence or live decoder performance. The package includes three figures, matched features, forecasts, fitted models, source hashes, and code. A fresh SEEG download rebuilt the feature tables exactly.

    We used the matched feature tables, source metadata, source manifest, EDF extraction code, retrieval code, and logistic fitting functions. A fresh download rebuilt the features exactly. The new test separates retention flags from history and voltage power, on the same cohort and outer split.

    The trial matching audit informed the use of source trial IDs to join channels. We checked these IDs and labels again. Its numerical results were not input data.

    The analysis used the processed SEEG dataset, version 1.0.1, with source trial IDs assumed to give task order.
