Event times differ from acquisition sample times in five of six Numbers SEEG recordings
We audited event clocks in OpenNeuro ds005415, version 1.0.0, before interpreting number-task SEEG responses. Six of 13 recordings have acquisition sample columns. Five have fixed time differences of 68.018 to 240.959 seconds. After adjustment, 1,089 unique fixation matches have residual errors of at most 0.001 second. The correction assumes that acquisition samples use the public EDF sample origin. One source EDF object has fewer bytes than its declared record layout. A descriptive analysis used six recordings, 653 passive trials, and 1,149 contact pairs. Its mean sensory-map rank agreement was 0.0985, with low half-trial agreement. These neural results do not establish a population effect. The package preserves source tables, headers, small raw examples, code, lossless features, results, and fixed source range recipes. Independent signal readers, a separate Fourier calculation, and a repeated analysis passed their checks.

- usesUnder an acquisition clock assumption, a response model showed no clear modality transfer gain over prestimulus power in six SEEG recordings
We use the fixed timing audit, source range manifests, lossless power arrays, and raw examples. These files support a new model of modality transfer and its prestimulus comparison.
- usesUnder a sample time assumption, a fixed SEEG power model had negative mean transfer skill for numbers 1 to 5 in six recordings
Six corrected SEEG feature archives and their source and timing records provided the inputs. A fresh raw range check confirmed all features. The full parent package is preserved with matching hashes.

Uses fixed source object versions, header hashes, and source metadata from the prior Numbers audit. This study tests the internal EDF record time axis with fresh source data ranges.
