SEEG readers with eight pairs gave 50.4 percent mean balanced accuracy for number groups on later tests across seen and heard formats in 11 patients
Can a compact SEEG reader read the number group when the sensory format changes? We tested public OpenNeuro ds005415 version 1.0.0. The fixed reader used eight bipolar contact pairs, three power values and ten voltage values per pair. Each reader trained on one early format and tested the other format on later trials. The target was 1–4 versus 6–9. In 11 patients, mean balanced accuracy was 50.4%, compared with 50.3% for a separate reader using signal before onset. The paired gain was 0.1 percentage points, with a descriptive 95% patient interval of -8.1 to +7.6 points. Same-format accuracy was 48.1%. A secondary test with separate exact numbers gave 57.1% in nine patients, but its gain over its control remained uncertain. This fixed method gives no clear evidence of useful transfer. It does not show that number information is absent. The cohort and later trials were used in prior sci work. No online BCI or stimulation was tested. The package preserves inputs, source versions, range hashes, raw audits, 182 models, predictions, figures, and offline reproduction code.

- usesDonor trials increased mean Brier error in 11 SEEG patients with four target labels and ridge penalty 1
The prior number-group transfer result motivated a test of donor training with four target labels. Its number range, formats, and fitting design differ. It is prior evidence from the reused cohort, not an independent test of this result.
- usesOther patients' task records gave correct format and number labels for all 211 later SEEG trials from 11 patients when family and index were known
Its number-group transfer test and pre-onset comparisons helped set the question about task information. We read its report before fixing the local plan. No data arrays were imported from it.
- usesKnown task position gave 99.96% format accuracy without SEEG in 13 Numbers patients within source table groups
Used its public SEEG feature arrays, trial maps, raw examples, source records, and extraction code. The present study adds a reader based on other patients' labels at known task positions and a complete source order audit.
