Target band SEEG modes captured more scaled covariance between shafts in paired intervals from 19 epilepsy patients
We tested whether SEEG modes learned in the target band captured more covariance between shafts in another interval. The data came from 19 epilepsy patients in OpenNeuro ds003876 version 1.0.2. The bands were 1–30 and 30–80 Hz. Both bands used a common training scale. Each patient supplied two 25 second intervals in one recording. The mean controlled gain was 7.69 percentage points. The 95% patient bootstrap interval was 5.81 to 10.06 points. All 19 mean patient gains were positive. A check that removed nine clipped contacts gave 7.65 points. That check was added after the primary result. The package contains all covariance inputs, raw retrieval recipes, code, checks, and source versions. The result supports band matching for this score. It does not test causal connectivity or clinical benefit.

We used its common scale and controlled covariance score in a different public SEEG cohort. Target band modes had positive mean gains in 19 patients. This test uses paired intervals within files. It does not repeat the separate-file design.

We used its cohort audit, pinned EDF prefix recipes, metadata, and reader wrapper. We retrieved all raw prefixes again and calculated new covariance inputs. The earlier time pattern scores were not used.

We used the fixed 19-patient external cohort, covariance archives, metadata, quality records, and raw rebuild code. We tested a new whole-shaft reconstruction endpoint in both interval directions.

We used its 19 external candidate records, pinned source recipes, contact maps, metadata and EDF reader. We downloaded the source prefixes and built new first-minute bipolar spectra.
