Offline SEEG models increased mean choice AUC by 0.101 after movement within visual directions in six additional MetaRDK participants
We compared processed high-gamma SEEG before and after movement in public MetaRDK data. The plan selected seven additional participants. Six passed the fixed trial rules. Each logistic model used eight bipolar channels. Early trials were used for fitting. Later trials were used for testing. Choice AUC gave equal weight to each visual direction and each participant. Mean AUC was 0.447 before movement and 0.548 after movement. The paired change was +0.101, with a participant bootstrap 95% interval from 0.055 to 0.152. The exact two-sided sign-flip p value was 0.0312. The interval excludes zero for this tested participant subset. The after-movement AUC interval is 0.482 to 0.638. It includes 0.5, so the paired gain alone does not establish reliable choice reading. The source uses a 400 ms smoothing filter, so these offline scores do not establish live command timing. The package adds seven verified compact feature files, records all exclusions, and preserves code, source versions, probabilities, models, figures, and instructions. It also reproduces the saved primary probabilities for 14 prior participants.
