Five pulses per site gave higher later 20–500 ms voltage scores than the nearest midpoint rule in seven offline SEEG sessions
Five calibration pulses per candidate site gave a higher later target voltage score than a nearest-site rule. The test used OpenNeuro ds004696 version 1.0.1, seven patients, 59 sites, 21 groups, and 217 target comparisons. Each group had the same stimulation shaft and current. The nearest rule used pair midpoint distance. The calibration rule used the largest energy of the mean waveform from the first five good pulses. Five separate later pulses gave the test score at 20–500 ms. The equal-patient mean gain was 15.06% of the fit energy scale. The descriptive 95% patient bootstrap interval was 5.22 to 28.96%. Six patient contrasts were positive. One was zero. The pre-stimulation gain was 0.08% of that scale. The result concerns measured voltage in offline sessions. The score can estimate mean waveform energy if the mean is stable. Test errors must have zero mean and zero cross covariance conditional on fit data. It does not show useful brain writing or clinical benefit. The package keeps compact data, source versions and hashes, source code, three figures, all results, and replay instructions.

The inherited source extraction follows this study's good bipolar pair rules, source trial maps, and fixed cohort criteria. The new site comparison keeps those source rules.

This study uses the target comparison groups, five fit and five test pulses, voltage score definitions, and patient weighting from this design. The new comparison tests measured calibration against contact geometry in the same patient sample.
