SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

EEG researchers often struggle to transform raw electrophysiological recordings into clean, analysis-ready data because each preprocessing choice—filters, artifact removal, referencing, epoching—introduces domain-specific trade-offs that can distort event-related potentials or time-frequency estimates. This Skill encapsulates expert judgment on ordering, parameter selection, and quality control so you can avoid common pitfalls like inappropriate high-pass cutoffs, premature interpolation, or unvalidated artifact rejection criteria. Follow the research planning and verification notices built into the Skill to ensure every decision is justified before execution.

Core Features & Use Cases

  • Structured pipeline planning: Step-by-step guidance from raw data import through bad channel handling, filtering, re-referencing, ICA/ASR cleaning, interpolation, epoching, and rejection, aligned with best practices from Luck, Onton & Makeig, and Bigdely-Shamlo.
  • Artifact management decisions: Compare ICA algorithms (Extended Infomax, AMICA, PICARD), ASR burst thresholds, and ICLabel classification cutoffs while understanding when to combine automated and manual cleanup.
  • Reporting and validation support: Built-in checklists for filters, line noise removal, referencing, ICA/ASR parameters, epoch rejection, and software version reporting keep your methods transparent and reproducible.

Quick Start

Ask this skill to walk you through EEG preprocessing steps from filtering through artifact rejection for your ERP study.

Frequently Asked Questions about EEG Preprocessing Pipeline Guide

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build an EEG preprocessing pipeline for ERP analysis?▼

Select ICA algorithms like Extended Infomax, AMICA, or PICARD for EEG artifact rejection based on your dataset characteristics. Combine these with ICLabel classification cutoffs and ASR burst thresholds to effectively isolate and remove noise components.

What high-pass filter cutoff should I use for EEG preprocessing?▼

Choose high-pass filter cutoffs carefully during EEG preprocessing to avoid distorting event-related potentials. Inappropriate cutoffs introduce domain-specific trade-offs that can severely skew your time-frequency estimates and subsequent ERP analyses.

How does ASR artifact rejection compare to ICA for EEG cleaning?▼

ASR artifact rejection uses burst thresholds for automated noise removal, while ICA separates independent components for targeted artifact rejection. ASR handles intermittent artifacts quickly, whereas ICA with ICLabel provides precise classification of brain versus noise sources.

What are the limitations of automated EEG artifact rejection?▼

Automated EEG artifact rejection using ASR or ICLabel has limitations if parameters are unvalidated. Premature interpolation or overly aggressive epoch rejection thresholds can distort data, requiring manual cleanup validation to ensure reliable time-frequency results.

Do I need a reporting checklist for EEG preprocessing parameters?▼

You need a reporting checklist for EEG preprocessing parameters to keep methods transparent and reproducible. Documenting filter settings, ICA algorithms, ASR thresholds, and software versions fulfills established methodology requirements for publication.
