Two references gave 33 stable beta loss labels each and shared 21 under a 1 dB rule in OpenNeuro ds004473, version 1.0.2

This study tested reference choice in eight public SEEG recordings from OpenNeuro ds004473, version 1.0.2. It used 1,990 response trials and 822 matched contact pairs. Common average and bipolar references each gave 33 stable beta loss labels under a 1 dB rule in both trial halves. They shared 21 labels and differed on 24 pairs. The three participant tests did not show a clear median beta change or a clear reference difference after Holm correction. A metadata check also found 27 response labels without recorded key presses; 26 passed the source trial mask. The package contains code, trial power arrays, source hashes, raw checks, and retrieval commands. These results apply to the sampled contacts in people with epilepsy. They do not prove reference equivalence or a motor cause.
