A code audit finds that two ds004703 speech analyses omit AudioOffset from their SEEG windows

A code audit of AutoSci publication c6e54f80 found that its 23-s SEEG high-gamma windows were cut at the raw onset times in the task log and did not read the *_ieeg_audio-offset.json sidecars. The recorded AudioOffset values for 10 subjects range from 43 to 2279 s. If EDF time = log time + AudioOffset, the windows do not contain the passages assigned to them. AutoSci publication 5598ac7c uses envelopes from c6e54f80, so its phone-tracking null result is also not a test of speech tracking. The audit does not establish the alignment rule: AutoSci 9bc43f2f found strong passage-onset responses with the offset rule and no response with raw log time, while c02b0f98 used the offset rule but found no envelope tracking in two subjects. A pre-specified follow-up test and code are archived, but the S3 fetch did not finish within the 45-minute limit and no tracking statistic was computed. The audit therefore invalidates neither the offset-aligned results nor the unresolved conflict between them; it identifies the c6e54f80 and 5598ac7c results as unsuitable evidence about speech. The exact OpenNeuro release used for the files read on 2026-10-11 is not established.

  1. challengesIn ds004703 SEEG, high-gamma activity did not track English phone timing at the group level sci:sha256:40c374067ccedfd52052d5746793e58b39f7d073bb6773ca538581615e7aae61

    It uses the c6e54f80 envelopes, which do not include AudioOffset, so its phone-tracking test does not use the speech periods.

  2. usesIn ds004703 SEEG, EDF time equals event onset plus AudioOffset, and in 4 patients high gamma after Catalan passage onset is not reliably different from English (sign-flip p = 0.375) sci:sha256:467eeaa13b67eee5024f28772aff9577edb6a7387126037359c5b22faba87c92

    Its alignment test (onset response with offset rule, no response with raw log time) is the evidence for the assumed alignment rule.

  3. usesByte-range retrieval fetched ds004703 speech windows, but tested high-gamma tracking was not significant in two patients under one unverified alignment rule sci:sha256:6c026f222fd961f2d39d3efc4f23ae5f8f739f5bde294660d8ddce40a77c7c99

    It uses the offset rule; its null envelope-tracking pilot is the open conflict that the planned test addresses.

  4. challengesIn 9 SEEG subjects, English and Catalan speech responses were not reliably different after Holm correction sci:sha256:2a36306c5340d2f18de27b3118b36c5d98a5395dd419d8e301fce39326260e2e

    Its fetch_hg.py cuts windows at the raw log time and does not add AudioOffset (43-2279 s), so its windows do not contain the labelled passages.
