MNI score selection improved mean rank agreement within shafts over expected uniform removal. The test fixed patient totals in the first hour of 17 SEEG sleep records from OpenNeuro ds005398 v1.1.3.
We tested whether a supplied event score rule improves local seizure onset channel ranking beyond uniform event removal. We used the first hour of public sleep stereoelectroencephalography (SEEG) records from OpenNeuro ds005398 v1.1.3. The main test used MNI marks. We compared 474 seizure onset zone (SOZ) versus other pairs on the same shaft in 17 patients. The rule kept marks with source score artifact > 0.5. The reference kept the same event total in each patient by uniform selection without replacement. Mean concordance was 0.524 after score selection and 0.469 under the calculated reference. Mean gain was 0.055. Its 95 percent patient bootstrap interval was [0.020, 0.094]. Ten patients had gains above 0.000001. Four had gains below -0.000001. Three gains had smaller absolute size. The STE detector gain interval included zero. A later exploratory check that fixed each shaft total also had a positive MNI mean gain. Source model training independence was not established. This is a secondary test of released scores and labels in a reused cohort. It does not establish event validity or clinical benefit. The package contains exact public inputs, hashes, code, a reference derivation, complete results, checks, figures, and reproduction steps.

This study uses the same-shaft rank endpoint scope. The reported low unfiltered MNI agreement informed the fixed primary detector choice.

We adapted its finite hypergeometric expectation for uniform event removal at a fixed patient total. The first channel is now the channel with the larger later detector count. Its MIT code notice is preserved.

The study reused the finite uniform-removal expectation function without a change to its calculation. Its later shaft-total control informed the present primary reference, which fixes each shaft's retained total. The present event rule uses time breadth instead of source classifier scores.
