Variation in four early pulses gave lower SEEG error-limit scores than response energy at 20–500 ms in five patients

We compared two local error scales in public SEEG data. Four early pulses fit a waveform forecast and a scale at each site. We tested four later pulses at 183 sites in five patients. Each patient limit used donor errors from the other four patients. At 20–500 ms, early pulse variation reduced the mean error-limit score by 20.7% compared with response energy. It reduced the mean RMS radius by 22.8%. The score was lower in all five patients. Mean complete block coverage was 90.4%, but two patients were below the requested 90% level. The gain was smaller with recording pairs that did not share contacts. The pre-pulse control favored energy on cost. Site exchangeability was not established. The study does not establish coverage in a new session or live interface performance. The package contains four figures, code, data, source hashes, and reproduction commands. Fresh raw downloads rebuilt all ten input files exactly and reproduced all 35 numerical result files.
