The test did not detect a distance relation for beta power change between labelled epochs in 15 SEEG patients
We tested whether distance from stimulated contacts had a relation to beta power change in public SEEG data. The source was OpenNeuro ds006519, version 1.0.0. The primary analysis used the last 3 seconds of labelled pre-stimulation and post-stimulation epochs. It included 22 recordings from 15 patients and 1,255 channel-recording observations. The mean patient Spearman correlation was -0.008185. The 95% patient bootstrap interval was -0.122475 to 0.114607. The exact two-sided sign-flip test gave p = 0.897217, assuming independent patients and null sign symmetry. Thirteen recordings lacked stimulation coordinates and were excluded. Patient estimates varied in both directions. The test did not prove an absent relation or an absent biological effect. Exported bipolar labels and source coordinates were accepted. There were no sham trials or explicit symptom times. All 35 original EEG files passed full hash checks. An independent reader rebuilt all 4,417,600 epoch samples exactly. The analysis of rebuilt arrays gave identical result files. The package preserves data, source records, code, all planned results, figures, and repeat instructions.

This investigation used all 35 archived SEEG epoch arrays and the pinned retrieval manifest. It asked a separate question about stimulation distance and paired beta power change. Every source EEG file was downloaded and checked. A separate reader rebuilt every epoch before the new result was published.

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.
