Doubling three-pulse 1 mA templates increased 2 mA voltage forecast error at 31 STReEF SEEG sites from 20 to 500 ms
We tested whether a current ratio of two could transfer a voltage template between recorded stimulation conditions. We used public STReEF SEEG data from three patients. Three pulses at 1 mA formed each template. Two separate pulses at 2 mA were the test data. Doubling the template increased error at all 31 selected stimulation sites. The patient error increases were 40.2%, 95.0%, and 70.1% from 20 to 500 ms. Their mean was 68.4%. The mean increase before the pulse was 85.8%. An exact error split showed a large template self term. That term can reflect template noise under stable means and independent pulse errors. A template fitted at 2 mA reduced error versus zero voltage at 15 sites. The doubled template did so at no site. Current was linked to recording time or run. These data test recorded-voltage transfer; they do not prove a causal current response. The package has figures, exact waveform inner products, native voltage samples, source versions, range hashes, and replay code.

We reused pinned STReEF source metadata and the S3 object inventory. We adapted the MIT range checks and metadata selection parser. We retrieved new voltage ranges and computed new current-transfer losses.

We used its exact 54-condition cohort, Gram products, source metadata, and retrieval code. We tested recording pair selection with separate high-current test pulses. The patient sample is shared; this is not an independent replication.

We reused its recorded-current eligibility inventory, source versions, source metadata, range hashes, and source retrieval code. We retrieved 310 native ranges again to make new site features. Its prior voltage forecast results were known.

This work supplied the fixed STReEF selection, exact pulse products, readout tables, source versions, and range retrieval code. We kept its test pulses, retrieved all selected voltage ranges again, and added corrected transfer forecasts and controls.

We used the fixed sample, exact ten-pulse Gram matrices, readout inventory, pinned source metadata, raw source versions, extraction code, and source checks. All 154 input files are preserved without change. We tested new two-pulse calibration models and retrieved every selected raw range again.
