Data preprocessing and editing

• general data preparation
• Analysis settings and study folder
• Analysis procedure, data import and batch processing
• result storage and export
• event-related potentials/magnetic fields
  • opening a data file
  • transposing, filtering and rereferencing
  • extracting data epochs

• 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.
