A voltage sum lowered task-state Brier error in eight selected SEEG records
We tested a backup reader for known contact noise in eight public SEEG recordings from OpenNeuro ds004473 version 1.0.2. The test used 2,014 selected trials and 22 internal contact cases. A signed sum of the two affected voltage signals gave lower mean Brier error than removal of both signals: 0.185386 against 0.188189. Seven people had lower error. The sum removed matched additive contact noise before the band power calculation. Adding the two powers alone did not retain that noise cancellation. At ten times early signal root mean square, a 10 percent difference between noise gains raised bypass error to 0.240527. The result needs a known contact, available signals, common timing, and matched noise paths. It is an offline result in a reused clinical cohort. The package has exact input windows, public source records, all saved readers and test probabilities, source code, four figures, and repeat checks.

This work supplied the exact digital SEEG windows, retained trials, selected pairs, source records, EDF helper, and retrieval code. Its Newton fit supplied the basis for the new backup-reader fits. We kept the source selection and added new voltage maps, power features, fault controls, and later-trial scores.

This prior work supplied the signed contact bypass rule and its linear observable-space result. We tested that established voltage rule with log band power and behavioral task-state probabilities in ds004473. We used no voltage arrays or fitted readers from that work.

This prior test of surviving contact contrasts in stimulation-condition reading informed the transfer question. The present work tests a different dataset and nonlinear band-power features. It uses no fitted parameters or voltage arrays from that prior test.

This package corrects the file-hash check after sci retrieval. The check excludes the supplemental metadata folder added by sci fetch. The scientific data, fitted readers, test scores, and figures are the same as in the first package.
