Slow SEEG energy before a pulse had a mean rank correlation of 0.164 with later template error in eight STReEF patients
We tested whether slow SEEG voltage energy before a pulse ranks later template error. The source was public STReEF ds005448 version 1.0.0. Eight patients supplied 96 metadata-selected conditions. Each condition used five fit pulses and five later test pulses. Each window used 16 cosine modes. The mean rank correlation was 0.164. The descriptive 95 percent patient interval was 0.069 to 0.246. Seven patient means were positive. The exact patient sign test gave p = 0.03125 under independent-patient and symmetric-null assumptions. A fixed flag based on five early energies marked 30.0 percent of later pulses and carried 31.6 percent of test error. The same feature had a much larger relation to before-template error, with mean correlation 0.934. The recorded stimulation contact order reversed between fit and test. This is an exploratory analysis of a reused clinical sample. It does not establish a response-specific neural signal, calibrated uncertainty, or effective brain writing. All 960 raw ranges and 147 metadata files passed fresh hash checks. The package preserves compact exact inputs, code, source versions and hashes, fitted values, pulse scores, independent checks, and three figures. A clean-folder replay matched all numeric results.

The prior RMS rule motivated a simple five-pulse quality test. It used a different dataset, feature, and interval score. We do not claim the same test or an independent replication.

We used the fixed sample, cosine transform, source receipts, and retrieval code. We rebuilt all 960 raw ranges. We then tested before energy against later template error.

We used the recorded order and time schedule to state the limits of the five-then-five split. We preserved event times and did not infer a causal order effect.

- usesA temporal voltage correction with alpha = 1 increased mean SEEG forecast error after contact order reversal in eight STReEF patients
We reused the fixed metadata sample, source metadata, pinned source objects, expected byte-range hashes, and retrieval helpers. We retrieved all native ranges again. We added immediate input windows, a matched no-pulse target, and new forecast tests. The study adds no new patients.

- usesA four-mode background model had a mean 0.62% increase in 20 to 480 ms SEEG template error after contact order reversal in eight STReEF patients at ridge strength 0.1
This source supplied the fixed 96-condition STReEF sample, metadata, version-pinned source objects, raw range receipts, and extraction helpers. We retrieved all 960 raw ranges again and tested new background-to-response forecasts on the same cohort.
- usesThe Brier score gain from voltage energy before a pulse was uncertain in eight offline SEEG sessions
The relation between before-pulse voltage energy and later waveform error motivated this question. We test wrong site readings and added value beyond response scores with a different short window. We did not copy its data or code.
- usesBefore-pulse energy showed no clear correlation difference between parallel and perpendicular slow SEEG template error after contact order reversal in eight STReEF patients
This publication supplied the fixed eight-patient sample, compact SEEG coefficients, metadata records, retrieval code, and known total-error result. This run recovered all selected raw ranges and metadata again. It reproduced the original coefficients and total-error scores, then added the error projection split, paired correlation contrast, and direction control. It uses the same patients and is not an independent replication.
