Galea Sample Dataset
To see an in-depth walkthrough of the Galea GUI's data and software features, watch this video.
What does Galea data look like?
When running Galea, the GUI will export the data as a .txt file, which can be converted to .csv or any other format depending on preference.
Format:
- Each row is one data sample (samples come in blocks of 256, fs = 250 Hz)
- Channels denoted in columns (EMG, EOG, EEG, PPG, EDA), as well as timestamp
- Note: EXG Channel 0 corresponds to Channel 1 in the GUI
See the table below to preview the dataset format. There are many columns, so you can scroll right to view the entire table.
