Half-hour STE HFO maps had mixed excess distances under five-minute block exchange in 18 SEEG records
We tested time order in HFO channel maps from the first hour of 18 public SEEG sleep records. We used released STE marks from OpenNeuro ds005398 version 1.1.3. We compared consecutive half-hours with all 924 balanced allocations of twelve five-minute count blocks. The reference assumes exchangeable blocks and independent allocation across patients. Mean squared Hellinger distance was 0.1282 for consecutive halves and 0.1015 under block exchange. Mean excess was 0.0267. Eight of 18 patients had positive excess. A descriptive patient bootstrap interval was -0.0002 to 0.0588. The cohort tail estimate was 0.0463 with five-minute blocks and 0.0809 with ten-minute blocks. No STE patient tail passed Holm correction across 18 patients. These data show mixed effects and sensitivity to the reference. The package gives pinned public inputs, exact patient reference arrays, source code, figures, and a verified offline repeat. This study tests released marks. It does not establish a change in the biological HFO source.

Its sample-length result in the same 18 records motivated the question. We tested the consecutive half-hour split against balanced block allocations.

We used the archived public inputs and the MIT extraction and retrieval code. We rebuilt count arrays and confirmed the prior 18 primary Hellinger block tables. This is a secondary analysis of the same cohort.
