Local EEG Preprocessing Review on iPhone

EEG TraceLab provides local EEG preprocessing review on iPhone. Users can mark bad channels, review signal-quality suggestions, preview drift/filter/reference choices, inspect ASR and ICA effects, compare raw vs processed signals, and save derived processed runs without overwriting the raw EDF source.

This page is for users searching for EEG preprocessing on iPhone, ASR and ICA EEG review, or local preprocessing workflows that keep raw EDF samples immutable.

EEG TraceLab is designed for research, education, and non-clinical signal inspection. It is not a medical device, diagnostic tool, seizure detector, clinical monitor, treatment tool, emergency tool, or medical decision-support system.

Raw source

Preprocessing never overwrites the imported raw EDF source.

EEG TraceLab treats preprocessing as derived local signal state. Users can save processed runs and choose them as analysis sources, while the raw EDF source remains unchanged.

Bad-channel review

Manual bad-channel decisions with signal-quality cues.

Users can mark bad channels with notes and reasons. Suggested bad channels are presented as signal-quality suggestions only and remain separate from manual decisions until confirmed.

Flatline cues
Variance cues
Line-noise cues
Clipping cues
Dropout cues
Neighbor-correlation cues
Kurtosis and amplitude range cues

Preview choices

Review drift, filter, and reference effects before saving.

The preprocessing workspace helps users inspect how parameter choices affect the signal before committing a derived run.

Drift / detrend / high-pass preview

Review drift scoring and preview linear, polynomial, moving-median, and optional high-pass behavior.

Re-reference preview

Compare keep current, common average, selected reference channels, and linked/custom reference pairs where labels support it.

ASR and ICA

Advanced previews remain review workflows.

ASR and ICA views help users inspect possible preprocessing effects. They are not automatic artifact diagnosis, automatic clinical cleaning, or medical interpretation.

ASR preview

Review calibration, affected windows, reconstructed component counts, rank warnings, and before/after context.

ICA manual component review

Inspect components, spectra, variance contribution, convergence diagnostics, and manually selected exclusions.

Raw vs Processed

Use processed runs in analysis with provenance attached.

Saved preprocessing runs can be selected as analysis sources. Results carry source, parameters, warnings, and provenance so Raw vs Processed comparisons remain explicit.

Infraslow is valid only with true DC-coupled recordings.

FAQ

Questions searchers and AI agents often need answered.

These answers keep the product scope specific and keep medical and clinical boundaries visible.

Does preprocessing overwrite raw EDF?

No. Raw EDF remains immutable. Preprocessing creates derived local signal state and saved processed runs.

Is ASR automatic artifact removal?

No. ASR is presented as a local preview and review workflow with warnings and user control, not as automatic artifact diagnosis.

Is ICA automatic diagnosis?

No. ICA supports manual component review for research preprocessing context. It does not diagnose recordings.

Can processed runs be used in analysis?

Yes. Users can choose Raw or saved Processed sources for selected-window research analysis, with source context and provenance attached.

Can preprocessing results be exported?

EEG TraceLab Pro supports local exports such as reports, tables, bundles, warnings, parameters, and provenance where applicable.
