A joint SEEG rank check gave a positive adjusted change in six of eight sessions after contact order reversal at 20 to 500 ms

We tested a joint waveform rank check in eight public STReEF SEEG sessions. The fixed subset had 96 conditions. Three early pulses formed the reference. The check flagged 176 of 480 reverse-order pulses (36.7 percent) and 43 of 192 held-out same-order pulses (22.4 percent). After subtraction of the before-pulse control, the equal-person change was 11.5 percentage points. The descriptive 95 percent person bootstrap interval was 1.6 to 20.8 points. The planned two-sided sign-flip p value was 0.0625. Six of eight adjusted changes were positive. Contact order and time changed together. The check missed most reverse-order pulses. These data do not establish a causal contact-order effect or online BCI benefit. The package preserves the protocol, exact pulse products, source versions, code, all rank outcomes, and two figures.
