Beta power before fixation did not improve nested ridge prediction of log reaction time in eight ds004473 patients
We tested beta power before fixation in public SEEG dataset ds004473, version 1.0.2. The sample contained 1,988 response trials and 822 contact pairs from eight patients. A context model used task settings and the previous reaction time. The added beta features used nested ridge regression with contiguous test sections and removal of nearby training trials. Prediction error was measured as squared error in log reaction time. The mean relative error increase was 0.25 percent, with equal weight for each patient. Seven patients had more error. One patient had equal error. These results apply to the early beta window, these contacts, and this model within the same session. They do not exclude useful beta bursts or later windows. The package preserves inputs, source hashes, code, numerical checks, raw retrieval instructions, and all test predictions.

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.

We used its trial power arrays, contact pairs, source masks, event audits, raw feature code, and byte range manifests. These inputs enabled a new test of reaction time prediction. We verified all source package hashes. We reproduced one raw trial with independent tools and all sub-1 features from fresh source byte ranges.

We used its description as context for the earlier beta window and as the source of two response audit concerns. We read it after our primary result. It prompted two marked exploratory checks of response keys and very short latencies. Our later window association test has a different estimator from its nested prediction test.
