The final_files/ Folder

Although not part of the strict BIDS standard, AutoCleanEEG provides a final_files/ folder inside the bids/ directory. This folder is meant as a convenience export: it gathers the most useful processed outputs in one place, so users can quickly start analysis without digging through derivatives or raw-like structures. 
bids/
└── final_files/
    ├── 128_Rest_EyesOpen_D1004_processing_log.csv   (CSV summary of preprocessing)
    ├── 128_Rest_EyesOpen_D1004_processing.log       (detailed step log)
    └── 128_Rest_EyesOpen_D1004_comp_epo.set         (cleaned & epoched EEG dataset)
This shows the three main items that typically appear:
  • *_processing_log.csv → concise summary table of the preprocessing run
  • *_processing.log → step-by-step log output
  • *_comp_epo.set → final, artifact-cleaned and epoched EEG dataset (EEGLAB format)

​
Why it exists

  • Convenience: Many users just want the “final” artifact-cleaned, epoched dataset without extra navigation.
  • Reproducibility: Logs are included alongside the cleaned files for transparency.
  • Compatibility: Outputs are still linked to the BIDS dataset, but collected in one easy-to-access folder.
This folder is not BIDS-compliant and may not be recognized by external BIDS validators.
It is provided purely for user convenience. For strict BIDS workflows, always use the sub-*/ and derivatives/ folders instead.
