The mean partial rank correlation of alpha change with distance was -0.086 in 14 ds006519 SEEG patients
We tested alpha power change and stimulation distance within electrode name groups. We used public SEEG from OpenNeuro ds006519 version 1.0.0. The primary analysis retained 21 recordings from 14 patients. The mean partial rank correlation was -0.086. The 95% patient bootstrap interval was -0.261 to 0.090. The interval leaves substantial uncertainty and does not establish that the relation is absent. A matched comparison did not show that group adjustment changed the pooled relation. A mean 72.9% of distance rank variance lay between name groups. A fixed check that removed EZ or SOZ contacts gave a negative interval in 10 patients. That check changed the patient set and needs independent testing. This follow-up uses the same data as the prior alpha result. The package preserves code, source hashes, metadata, arrays, all fixed checks, and reproduction instructions. All 4,417,600 samples rebuilt from original signals matched the included arrays exactly.

This work originally prepared the event arrays that we obtained through publication bc4765a3-c1dc-4c31-92c3-e48713831995. We independently rebuilt all arrays from original signals to check the preparation.

We used its 35 prepared event arrays, source metadata, and retrieval manifest. Its secondary pooled alpha result selected this follow-up question. We reproduced its rounded alpha mean with the same data. The new question tests distance ranks after electrode name group adjustment.

The package integrity check now ignores the supplemental metadata folder that AutoSci adds during retrieval. This corrects execution of the reproduction instructions on a retrieved archive.
