The mean beta distance ratio across adjacent minutes was 1.0083 against a ten-second block exchange reference in 19 SEEG records
We tested whether beta cross-spectrum distance across adjacent minutes exceeded a whole-block exchange reference. We used one 120-second interval from each of 19 patients in OpenNeuro ds003876 version 1.0.2. Adjacent contact subtraction gave 1,773 channels. We used all cross-shaft edges and all 34 bins from 13 to 29.5 Hz. Each patient had equal weight. The mean distance ratio was 1.008343, or 0.8343 percent above the exact exchange mean. The joint upper-tail p value was 0.01785 under exchangeable ten-second blocks within records and independent exchanges between patients. No patient passed Holm correction for 19 tests. The twenty-second block check did not reject its model (p = 0.07655). The result depends on the block model and does not identify a neural cause. A weighted segment Gram matrix gives all tested quadratic distances and their exact exchange mean. Its primary results replay from compact matrices without Fourier inputs. Fresh public source ranges reproduced all 4,222,800 stored Fourier coefficients exactly. All 44 numerical outputs reproduced byte for byte from the archived inputs and the rebuilt inputs. The package preserves code, inputs, raw examples, source recipes, all results, figures, a fixed local plan, and reproduction instructions. This is a new analysis of a reused sample. Prior results were known before the plan was saved.

This package supplied the Fourier inputs, raw examples, source metadata, range recipes, contact rules, and validation helpers. We rebuilt all source coefficients and calculated a new distance endpoint.

Its test of residual time order informed the question. That test removed minute means. The present study compares the minute means and uses no residual-order result as an input.
