One log RMS value per pair reduced site accuracy in five SEEG sessions with a fixed reader
We tested two response representations with the same fixed site reader. The data came from five public SEEG sessions in OpenNeuro ds004457, version 1.0.2. The test had 183 sites and 732 pulses. Four earlier pulses per site fitted the reader. The response window was 20 to 100 ms. One log root mean square (RMS) value replaced sixteen signed bins per recording pair. Equal-session mean accuracy fell from 40.56% to 22.65%. All five sessions had lower accuracy. Feature count fell by 93.75%. The exact two-sided patient test gave p = 0.0625. Time-group RMS and absolute bins recovered part of the accuracy. The package has three figures, code, derived data, predictions, models, and source hashes. A raw rebuild and a fresh analysis reproduced the saved inputs and results. The evidence applies to the fixed reader and retrospective pulse split. The cohort and later pulses were used in earlier studies.

We reused its exact voltage files, selected recording contacts, eligibility rules, and pulse split. We used its fixed covariance reader. The signed primary correct counts match the earlier report. The new test compares fixed response representations.

Its study of numeric reader storage gave context for the feature-count question. We tested voltage size and time detail with the original pulse split and reader rule.
