Data preprocessing and editing

• general data preparation
• Analysis settings, workspaces and study folders
• Data import, batches and processing logs
• result storage and export
• ERP/ERF preprocessing
  • Prepare inputs and open a recording
  • Continuous preparation, rereferencing and filtering
  • Ocular correction: ICA and regression
  • Extract epochs and set their baseline
  • Calculate epoch statistics and channel proposals
  • Decide artefact thresholds and average trials
  • Flow control, review passes and reuse
  • Processing branches and subject overrides
  • Group conditions and select accepted trials
  • Processing Outcomes and Retained Trials
  • Files, cleanup and troubleshooting

• view epoch analysis
• view average analysis
• view sql analysis

Data preprocessing and editing is usually the most laborious part in the data analysis and is different for each type of signal. However, data preparation, analysis procedure and result storage are common to all signal types and are therefore explained in the first sections. Channel specific issues are explained in the following sections.
