phase-data-preprocess

The data-preprocess phase filters, cleans, epochs, and quality-checks raw data to produce analysis-ready datasets.

Approach

• Read .neuroflow/data/ inventory first — understand the dataset before choosing methods
• Confirm the modality; preprocessing steps differ significantly between EEG, fMRI, ECG, eye-tracking
• Document every parameter choice (filter cutoffs, epoch windows, rejection thresholds) before running
• QC plots and rejection summaries are required outputs — not optional

Relevant skills

• neuroflow:neuroflow-core — read first; defines the command lifecycle and .neuroflow/ write rules

Workflow hints

• All scripts and processed data go to output_path (scripts/preprocessing/), not inside .neuroflow/
• Save preprocess-config.md to .neuroflow/data-preprocess/ with the full parameter set used
• Log any deviation from a pre-registered preprocessing plan in .neuroflow/reasoning/data-preprocess.json

Slash command

/neuroflow:data-preprocess — runs this workflow as a slash command.
