Six second block ranges had lower coverage between records for centered high gamma SEEG maps in 35 patients under common average reference

We tested a fixed nominal 95 percent range rule on 30 second high gamma SEEG maps from 35 patients in OpenNeuro ds004100 version 1.1.3. The maps used common average reference and contact mean removal. Six second circular blocks from each training segment set the range widths. Equal patient mean coverage was 68.3 percent in adjacent segments and 41.6 percent in the other source record. The decrease was 26.7 percentage points, with a 95 percent patient bootstrap interval of 21.5 to 32.0 points. Coverage was lower between records in 33 patients. A multiplier learned from other patients' adjacent segment errors gave 94.9 percent within record coverage and 78.6 percent between record coverage in held patients. This retrospective test shows limited transfer for the defined range rule. It does not identify a neural cause or test clinical outcomes. The package preserves power inputs, raw source recipes, range fits, simulation draws, independent checks, code, and reproduction instructions. All 254 numerical result file hashes matched in a full repeat.

Its same file and other file coverage test on centered high gamma maps informed the comparison question. We tested a different feature, reference, target duration, and interval rule. We did not use its power arrays or code.
