Source event rules change sampled 80 to 150 Hz power maps in five sleep files from three SEEG patients

Source event rules changed 80 to 150 Hz power maps in fixed samples from five sleep files in OpenNeuro ds003848 version 1.0.3. The files came from three SEEG patients. We used 156 bipolar pairs and 2,400 one-second windows. The primary rule retained 1,646 windows after source event selection. The map difference ranged from 0.01 to 2.20 dB RMS. The equal patient mean seizure onset zone AUC changed from 0.7185 to 0.6824. After selection, patient AUC values were 0.9722, 0.0750, and 1.0000. Thus, the power ranking had opposite directions across these patients. The AUC compares pairs within name groups that have both source label classes. The package preserves code, all window powers, masks, source metadata, raw sample clips, and fixed source retrieval rules. Independent numerical checks and a full offline repeat passed. These results describe the selected files and source annotations. They do not show a patient population effect or a clinical benefit.
