Combined HFO marks on contacts 1–2 had 44.8 percent direction agreement across dates in seven SEEG patients for 2–25 ms delays

We tested whether onset directions learned from early sleep dates predict directions on later dates. We used released combined high frequency oscillation marks from OpenNeuro ds003498, version 1.1.1. The primary sample included 135 records from seven patients, with contacts 1–2 on separate shafts and delays of 2 to 25 milliseconds. Each patient had equal weight. Mean direction agreement was 44.8 percent. The descriptive 95 percent patient resampling interval was 28.8 to 54.7 percent. The exact date-reversal test gave p = 0.41015625, under assumptions of independent date orientations and symmetry conditional on fitted directions. One patient had only two test matches; removing that patient gave 52.3 percent agreement. A secondary fast ripple check gave 55.4 percent agreement and unadjusted p = 0.03845215. No secondary date-reversal test passed a correction for 12 checks. The primary result did not show agreement above chance. Sparse matches limit precision. The findings do not establish that biological propagation is absent. The package preserves source marks, hashes, retrieval code, plan, results, figures, and repeat instructions.

usesUnder a block shift model, adjusted 25 ms HFO maps had a mean cosine of 0.502 across dates in seven SEEG patients
We read its cross-date onset-order direction study before the local plan. It informed the distinct question about undirected residual edge maps. The shared cohort prevents an independent replication claim.
usesCombined HFO timing maps on contacts 1–2 showed positive mean agreement across dates in seven SEEG patients under fixed count, shaft, and hemisphere controls
This work supplied the copied source reader, released date tables, and retrieval scripts. Its direction endpoint provided context for the new unordered map endpoint.

We read its across-date onset-order result after our first primary scores. It gives context from a different source. It did not change the fixed primary plan.
