Exported or converted CSV files contain the same descriptive tags and columns of data as the EDF files for EEG and motion data, but in CSV format. This data is usually not clean so some preprocessing steps are needed. The raw EEG signal is composed of many different frequencies, all in different relative quantities (we call the quantity of a specific frequency in the larger raw signal called the "power" of that frequency). Anesth Analg. The uploaded files named with raw suffixes contain all the signals. Raw EEG data is a complex wave form of not simply brainwave activity, but the electrical activity of nearby muscles, electrode motion interference and what is called “ambient noise” (caused by electrical supplies and appliances in the room).
