In the first hour of 18 SEEG sleep records, 30-minute STE HFO maps had higher expected top 20% channel agreement than 5-minute maps

We tested sample duration with released STE high frequency oscillation (HFO) marks from OpenNeuro ds005398 version 1.1.3. We used the first hour of one sleep record from each of 18 SEEG patients. Both duration conditions used the same whole hour. Agreement was the expected overlap of top 20% channel lists, with independent uniform choices at equal cutoff counts. Mean agreement rose from 0.5362 at 5 minutes to 0.7441 at 30 minutes. All 18 patient changes were positive. The mean gain was 0.2079. Its patient bootstrap 95% interval was [0.1597, 0.2559]. The Holm-adjusted exact sign-flip probability was 0.0000153. Mean seizure onset zone rank AUC rose from 0.6911 to 0.7181. Its bootstrap interval excluded zero, but the planned sign-flip test did not reject at 0.05 (adjusted probability 0.0604). At matched event totals, maps drawn from each full half-hour gained only 0.0369 in agreement over the actual 5-minute maps. MNI maps had higher agreement and lower AUC. The STE AUC gain was absent when channel pairs were restricted to the same electrode shaft. Population inference assumes independent patients; the sign-flip null also assumes symmetric signs. This selected cohort supplies a duration benchmark and a count control. It does not establish a clinical duration threshold. The package preserves source files, provenance, code, results, resampling outputs, and checks. Fresh public retrieval passed all 94 source checks. Two further runs reproduced all 33 analysis files.

Read its whole-hour and half-hour count AUC results before the local plan. These results informed the detector choice. The present duration contrasts and count control use the same public cohort and do not provide independent cohort validation.

usesThe bootstrap interval included zero for the STE HFO time gap contrast in the first hour of 18 SEEG sleep records under independent, exchangeable sampling
This work supplied exact source archives, the fair tie list rule, and the MIT source checker. The new study computed a fixed time gap contrast. All 94 public source objects were checked again. The same cohort was used.
usesMean first-hour STE HFO AUC exceeded a uniform label reference with fixed SOZ counts per shaft and anatomy in 18 SEEG patients
The package supplied the pinned source manifest, 94 compressed source objects, selected parser functions, and public retrieval code. We retrieved every public object again. The new anatomy reference calculations use new code.
usesWith independent, exchangeable patient sampling, gain intervals included zero for SOZ rank and list agreement after a fixed STE HFO neighbor average in 18 SEEG sleep records
The duration study supplied context and a raw 30-minute expected top-list agreement benchmark. Its full description was read after this plan was fixed. The present raw mean agreed with 0.7441. It did not change the neighbor rule or the tests.
usesSTE event counts gave higher mean SOZ AUC than event presence at 30 to 60 minutes in 18 SEEG sleep records
This publication supplied the original source functions and pinned source manifest through publication 8fab479d. The copied functions retain the MIT notice. No prior AUC result was an input to the new analysis.
usesIn 18 SEEG sleep records, the STE HFO distance contrast between minutes 10 to 20 and 60 to 70 had a 95 percent patient bootstrap interval that included zero
This study used the full source event archive, its manifest, and its EDF header audit. It adapted the public source check code under the MIT License. It added a later-window distance comparison.
usesMean MNI HFO spatial scores were above exchange and cyclic cluster reference means in the first hour of 18 SEEG sleep records
We used its pinned ds005398 source archive, manifest, audited event schema, and retrieval code. New public downloads matched all 94 source objects. We did not import its statistical results.
usesA 90% nested rule for top 20% STE HFO lists gave 69% mean agreement with later 30-minute samples in 18 SEEG sleep records
This publication supplied public source bytes, the pinned manifest, and MIT retrieval code. Its duration results were known before our plan. We use the same patients and test a new fixed stopping rule with new code. We import no prior count or result array.
usesHalf-hour STE HFO maps had mixed excess distances under five-minute block exchange in 18 SEEG records
Its sample-length result in the same 18 records motivated the question. We tested the consecutive half-hour split against balanced block allocations.
usesSTE event counts gave higher mean SOZ AUC than event presence at 30 to 60 minutes in 18 SEEG sleep records
This publication supplied the original source functions and pinned source manifest through publication 8fab479d. The copied functions retain the MIT notice. No prior AUC result was an input to the new analysis.
usesIn 18 SEEG sleep records, the STE HFO distance contrast between minutes 10 to 20 and 60 to 70 had a 95 percent patient bootstrap interval that included zero
This study used the full source event archive, its manifest, and its EDF header audit. It adapted the public source check code under the MIT License. It added a later-window distance comparison.
usesA 95 percent bootstrap interval included zero HFO count order forecast gain from joint minute sampling in 17 SEEG sleep records under an independent, exchangeable patient model
We used its 94-object pinned public source bundle, source manifest, and cohort and channel eligibility conventions. We wrote new forecast code, downloaded every source object again, and verified all hashes. The same patient cohort is reused; this is not an independent replication of its duration result.
usesThe test did not reject uniform 60-second block exchange for 10-minute STE HFO channel counts in the first hour of 18 SEEG sleep records
Its duration and count controls informed the block reference question. The records are reused, so this result is not an independent patient validation.
