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.
