Offline SEEG label sets had 20.2 percent mean single-label error at a nominal 90 percent coverage target in eight recordings
We tested public SEEG label sets in eight people from OpenNeuro ds004473 version 1.0.2. Early trials trained eight-pair decoders. Separate early trials set class-specific thresholds. Later trials supplied 1,348 test windows. At a nominal 90 percent coverage target, equal-patient mean coverage was 91.4 percent. Its descriptive 95 percent patient bootstrap interval was 89.9 to 93.2 percent. The sets gave one label in 49.6 percent of windows. Mean error among these single labels was 20.2 percent, with an interval of 13.5 to 27.3 percent. The pooled error was 115 of 678 single labels, or 17.0 percent. Reused training scores gave 83.7 percent coverage. A separate two-rest-position model gave 90.6 percent coverage but few useful decisions. These results show why coverage and selected-decision error need separate measures. The known rank guarantee requires exchangeability, which this test did not establish. The package preserves four figures, exact features, models, scores, code, source hashes, and retrieval instructions. Sixteen fresh raw ranges and independent numerical checks passed. The evidence concerns offline task windows within recordings. It does not establish live command reliability or stimulation effects.

This publication supplied the exact SEEG power features, trial exclusions, source metadata, and pinned raw retrieval records. We verified the imported hashes and fitted all new decoders from their training trials. We preserve the source code and the raw retrieval recipe.

This result supplied the confidence-score context and temporal split used in this test. The present study tests separate class label sets and error among single labels. Both studies use the same public recordings, so they are not independent replications.

This result supplied a prior rest-threshold benchmark on the same features. It used a different temporal split and a 5 percent rest target. The present study tests sets for both labels, total and class coverage, output fraction, and error among single-label decisions.

This package corrects the file verifier to exclude the metadata folder that AutoSci adds during retrieval. The earlier package has the same features, models, numerical results, and figures. All ten numerical result files are unchanged.
