A fixed low frequency score had higher mean contact rank agreement within runs than across runs in 56-second samples from 36 SEEG patients
We compared contact ranks for a fixed low frequency score in two public SEEG runs from each of 36 patients. The same 4,252 contacts were used in four 56-second samples per patient. Mean Spearman agreement was 0.472 within runs and 0.379 across runs. The paired mean difference was 0.094, with a 95 percent patient bootstrap interval of 0.051 to 0.138. All planned reference, band, duration, and sample-position checks retained the same direction. The clinical-label AUC-change interval included zero. The run time gap and recording states were unknown. This is a secondary analysis of archived public measurements. The package preserves code, source records, results, figures, raw validation samples, and reproduction instructions.

This secondary analysis uses all 72 archived window-power feature arrays, source contact metadata, matching rules, source hashes, and pinned raw retrieval code. It adds equal-duration within-run and across-run rank comparisons in the same 36 patients.
