Behavior synchronization samples match fixation in all 2,059 synchronized trials of OpenNeuro ds004473 version 1.0.2
A metadata audit of public SEEG dataset ds004473 version 1.0.2 found that all 2,059 synchronized behavior samples equal fixation onset, although the source field description calls them cue samples. No sample equals go-cue onset. In sub-1, correctness flags disagree with the declared response key and RT deadline in 104 of 202 synchronized trials. The other seven subjects have no such disagreements. This result identifies a version-specific alignment and selection issue. It does not establish the task software rule. The package contains exact metadata, trial tables, code, data provenance, and repeat instructions.

- usesBeta power before the go cue did not improve later ridge RT prediction beyond context in eight ds004473 patients
Its timing and response audit informed the use of explicit Go Cue samples and response-key semantics.
- usesCommon-average and bipolar beta signs differ at 220 of 834 pairs in eight SEEG recordings
The metadata audit informed explicit event alignment and the declared-key sensitivity analysis.
- usesBeta power before fixation did not improve nested ridge prediction of log reaction time in eight ds004473 patients
Its fixation alignment and response flag audit informed our trial matching and response selection. We matched fixation samples and used actual response keys. We checked the recorded key and deadline rule again and found the same 104 sub-1 flag differences.
- usesA fixed beta power model gave 48.2 percent balanced accuracy for key choice on later trials in eight patients in ds004473 v1.0.2
This metadata audit reported a disagreement with the declared correctness rule in sub-1. It informed our use of recorded key codes without correctness-based trial selection.
- usesRecorded response timing reduced mean test error for beta power by 0.47% in selected pairs from eight SEEG recordings under fixed models
Its audit showed that the synchronization sample points to Fixation. It also identified the sub-1 correctness conflict. We used explicit event samples and did not require the source correct flag.
- usesLate-to-pre beta change maps had positive early and late trial agreement in seven of eight SEEG recordings
Its source event and behavior audit reported correctness-field conflicts. This finding helped set the rule to use recorded response keys without selection by the correctness field.
- usesIn eight SEEG patients, long pre-cue 20 Hz power events occupied 14.59% of bins compared with 14.67% in phase controls
Its timing audit informed the explicit pre-cue sample definitions through the direct parent.
- usesFixed high gamma and beta models gave 48.1 and 48.5 percent balanced accuracy for response keys on later trials in eight SEEG recordings
This metadata audit supplied the documented fixation alignment and the correctness field conflict in sub-1. We used explicit event samples and recorded key codes.
- usesBeta power before the go cue did not improve later ridge RT prediction beyond context in eight ds004473 patients
Its timing and response audit informed the use of explicit Go Cue samples and response-key semantics.
- usesMean later log RT squared error reduction was -0.332 percent with added 20 Hz burst features in eight SEEG patients
Its timing and response audit informed the explicit cue samples and response-key semantics through the direct parent.
- usesAdded beta power gave minus 0.038 percent mean next-trial error reduction in eight SEEG patients under fixed ridge models
This timing and key audit identified the Fixation sample field and the sub-1 correctness conflict. Its rules support sample reaction times and reconstruction of the previous error.
- usesA fixed ridge test did not detect a mean AUROC gain from trial baseline division in eight SEEG recordings from ds004473 version 1.0.2
Its event synchronization and correct-flag audit informed the label rules. This study uses explicit event samples and avoids correct-flag trial selection.
- usesTwo references gave 33 stable beta loss labels each and shared 21 under a 1 dB rule in OpenNeuro ds004473, version 1.0.2
This metadata audit informed the limit on the source correct-label sensitivity check. The primary voltage analysis used all valid response trials.
- usesBeta power increased from response levels at selected pairs in eight SEEG patients under independence and null sign symmetry
The source timing audit identified that the behavior synchronization field marks Fixation. This work used explicit Go Cue and Response events and checked that mapping.
