A window before late Cue contained samples after recorded onset in 187 of 226 beep trials from six public SEEG runs

We tested whether a 500 ms window from 800 to 300 ms before an event named Cue was before beep onset. We used public OpenNeuro ds005415, version 1.0.0. In six complete SEEG runs, 187 of 226 windows contained samples after recorded onset. All samples were after onset in 121 windows. The late event delay depended on beep count. The source study recognized end-of-audio timing; this audit tests a possible misuse of that event. A fixed low-count versus high-count readout used 173 trials. Mean balanced accuracy was 36.1% before onset, 43.8% before late Cue, and 49.3% after onset. The paired difference was 7.64 percentage points, with a 95% run-bootstrap interval of -2.88 to 19.27 and an exact sign-flip probability of 0.34375. The signal test did not show a consistent increase. Recorded onset was not checked with a microphone. The package contains code, trial maps, source versions and hashes, features, models, null results, raw audit samples, three figures, and reproduction instructions. A fresh source extraction reproduced every feature array exactly.

Its description supplied checks for auxiliary sensors and shortened EDF contact labels before decoder scores. It also reported the short sub-80 source file. We confirmed that byte issue. We did not reuse its code, signal features, or readout results. Its test used visual number forms; this test uses beep trials.

usesA fixed SEEG reader gave 50.3% mean accuracy across formats on unseen numbers in eight patients
Uses Cue Start for spoken number onset, as checked by the timing audit.
usesTrend correction kept SEEG decisions fixed under added linear voltage drift with fixed power inputs in 11 patients
This study used its inherited pinned source object records, EDF headers, BIDS metadata, and event interpretation. The spoken-word onset uses Cue Start to avoid the late audio Cue problem.
usesPower plus voltage gave 57.0% balanced accuracy for later format reading in 11 SEEG patients with eight pairs selected from early power
Used source version records, EDF headers, BIDS metadata, and spoken-onset interpretation inherited through the immediate feature source.
usesA fixed SEEG reader showed no clear format gain after onset on unseen even numbers in 11 patients
This study uses the source clock checks and interpretation of the spoken Cue Start event through the parent package. These records support the trial maps and recorded-onset windows.
usesPost-onset SEEG inputs gave an uncertain format error reduction against duplicate baseline inputs in 11 patients at ridge penalty 1
Its onset audit supplied the recorded event rule inherited by the input extraction: Cue Start for spoken trials and Cue for written trials. The later spoken Cue is not treated as onset.
usesA fixed eight-pair SEEG reader reached 47.4% balanced accuracy between digits and spoken words on later trials in 11 patients
This study reuses the source object version records, EDF headers, and BIDS metadata from this timing audit. Its contact checks and interpretation of Cue Start enabled correct recorded-onset alignment for new spoken-number features.
usesA fixed SEEG sound versus image reader gave 48.4% mean balanced accuracy across formats on later trials in 11 patients
The audio timing audit guided use of Cue Start for spoken words and beeps. We also checked the derived late Cue against nominal source durations and disclosed a new event consistency exclusion after initial scores.
