Readers with up to eight motor and premotor SEEG channels gave 0.476 mean choice AUC within visual directions before movement in 11 MetaRDK participants
We tested a motor and premotor atlas rule for compact SEEG choice readers. We used public MetaRDK high-gamma data from OpenNeuro ds006253 version 1.0.3. The 11-person test used 907 later trials. Each reader used the same limit of three to eight channels for each person. Before movement, mean choice AUC within visual directions was 0.476 for the atlas rule and 0.509 for all matched brain channels. The paired difference was -0.033. Its descriptive 95% person bootstrap interval was [-0.078, 0.007]. The atlas rule gave no measured gain in this test. This does not prove equal performance. A channel audit found one unmatched marker feature in each of 14 inherited files. Its removal left all before-movement scores equal. The package preserves the channel masks, compact data, code, figures, predictions, and source records. All people were reused from an earlier study. Source smoothing and movement alignment limit the result to offline reading. The study did not test stimulation.

[Legacy relation: reproduces] We repeated all 126 inherited choice models. The selected channels, conditional AUC values, and test probabilities match exactly. This check uses the same data and splits.

We used all 14 compact signal files, behavior and anatomy tables, source receipts, choice inference, numerical solver, trial splits, and prior model states to test a fixed anatomy rule at a common channel limit.

The earlier marker-feature audit informs the source feature checks. We require both names in each bipolar pair to match the source anatomy table.

Its marker-channel audit prompted the requirement that both contacts of a candidate pair match the public anatomy table. The current parser and full channel audit are new.
