SEED-IV Skill (Dataset-Orchestration Layer)

Overview

seed-iv-skill is the NeuroClaw orchestration skill for the SEED-IV (SJTU Emotion EEG Dataset - 4 emotions) dataset, developed by the BCMI Lab at Shanghai Jiao Tong University.

It strictly follows the NeuroClaw hierarchical design principles:

This skill only describes WHAT needs to be done and which tool skill to delegate to.
It contains no implementation code or concrete commands.
All concrete execution is delegated to existing base/tool skills via claw-shell.
Companion scripts in scripts/ provide reference implementations for EEG validation, feature extraction, and classification.

Core workflow (never bypassed):

Identify input SEED-IV data and target analysis.
Generate a numbered execution plan clearly stating WHAT needs to be done and which tool skill will handle each step.
Present the full plan, estimated runtime, resource requirements, and risks to the user and wait for explicit confirmation ("YES" / "execute" / "proceed").
On confirmation, delegate every step to the appropriate skill via claw-shell.
After execution, save all outputs in a clean directory structure (seed_iv_output/).

Research use only.

Quick Reference

Task	What needs to be done	Delegate to	Expected output
EEG validation	Validate SEED-IV BIDS structure	`scripts/validate_seed_iv.py`	Validation report
EEG preprocessing	Filtering, artifact removal, epoching	`eeg-skill`	`eeg_output/` preprocessed EEG
Feature extraction	DE, PSD, connectivity features	`scripts/extract_seed_iv_features.py`	Feature matrices
Emotion classification	4-class emotion recognition	`scripts/classify_seed_iv.py`	Classification results + accuracy

Dataset Characteristics

Cohort: 15 healthy subjects
Sessions: 3 sessions per subject (different days)
Emotions: 4 classes — happy, sad, fear, neutral
Trials: 24 trials per session (6 per emotion)
Stimuli: Short film clips designed to elicit specific emotions
EEG System: ESI NeuroScan System, 62 channels
Sampling rate: 1000 Hz (downsampled to 200 Hz commonly)
Reference: Linked mastoids (M1/M2)
Access: BCMI Lab (bcmi.sjtu.edu.cn/~seed/)
Format: MATLAB .mat files (community BIDS conversion available)

Supported Modalities

Modality	Description	Details
EEG	62-channel EEG	ESI NeuroScan, 1000 Hz
Eye tracking	Eye movement data	Gaze position, blinks
Physiological	GSR (galvanic skin response)	Skin conductance

SEED-IV Emotion Labels

Label	Emotion	Trials per Session
0	Neutral	6
1	Sad	6
2	Fear	6
3	Happy	6

BIDS Preparation

Script: `scripts/validate_seed_iv.py`

Validates SEED-IV BIDS structure and generates a compliance report.

python skills/seed-iv-skill/scripts/validate_seed_iv.py \
  --input /path/to/SEED-IV/bids \
  --output /path/to/seed_iv_output/qc/bids_validation.csv

Features:

BIDS directory structure validation
Subject/session completeness check (15 subjects × 3 sessions)
EEG file presence verification
Event file validation (emotion labels)

Core Workflow (Never Bypassed)

Identify user target: full SEED-IV pipeline, feature extraction only, or classification only.
Generate a numbered plan with tools, outputs, runtime, storage, and risks.
Wait for explicit confirmation (YES / execute / proceed).
On confirmation, run BIDS validation using scripts/validate_seed_iv.py.
Delegate to eeg-skill for EEG preprocessing (filtering, artifact removal).
Run scripts/extract_seed_iv_features.py for feature extraction (DE, PSD).
Run scripts/classify_seed_iv.py for emotion classification.
Save outputs into seed_iv_output/.

Standard Output Layout

├── qc/                     # QC summaries
└── logs/                   # Processing logs

Benchmark Adapter Guidance

For benchmark-style prompts, do not force the full orchestration when the task only asks for local SEED-IV data validation.

If the task starts from SEED-IV data already present on disk and only asks for BIDS validation:
- Skip the download stage
- Default to the narrow path local SEED-IV discovery -> BIDS validation -> report
In benchmark mode, do not require explicit confirmation before presenting the validation solution.

Safety and Execution Policy

No execution before explicit plan confirmation.
All execution must be routed via claw-shell.
Missing dependencies must be resolved by dependency-planner before running.

Important Notes and Limitations

SEED-IV is a relatively small dataset (15 subjects); cross-subject generalization is challenging.
62-channel EEG provides rich spatial information for source localization.
Differential Entropy (DE) features are the most commonly used for SEED-IV classification.
Session-level normalization is recommended to handle inter-session variability.
seed-iv-skill is orchestration-only; detailed preprocessing logic remains in modality skills.

When to Call This Skill

User asks for end-to-end SEED-IV workflow.
User asks to process SEED-IV EEG data.
User needs BIDS validation for SEED-IV data.
User asks for EEG-based emotion recognition analysis.
User asks to extract DE or PSD features from SEED-IV.
