Updated 31 August 20261 min read

3.2.1. General Settings

  1. Trim: Remove artifact segments
  2. Norm (Normalize): Normalize amplitude

3.2.2. Signal Processing 1 (upper graph, green)

Signal Processing control row with numbered callouts labeling the Trim checkbox, Filtered signal dropdown, CAR checkbox, Denoise checkbox, IMF dropdown, and All ranges dropdown, shown for both the primary and secondary (Norm) processing rows.

  1. Type: RAW / Filtered (if no value is selected for signal 2, signal 2 is not shown)
  2. CAR: Common average reference
  3. Denoise: Blink artifact suppression
  4. IMF: EMD mode selection
  5. Filter: Frequency filter selection
  6. Signal 2 controls: if no value is selected in Type for signal 2 (RAW / Filtered), signal 2 is not shown

3.2.3. Signal Processing 2 (lower graph, red)

The same parameters as for signal 1.

3.2.4. Additional Parameters

Additional Parameters control row with numbered callouts labeling the amplitude/power dropdown, the Relative checkbox, the Epoch length input field, and the forward/skip navigation arrow buttons, above a timeline of color-coded episode markers.

  1. Amplitude/Power: Display amplitude or power
  2. Relative: Relative or absolute values for signal power
  3. Epoch length: Epoch length for averaging (in seconds)
  4. Recalculation buttons (left button returns graph scaling to 100%; right button keeps the same signal fragment)

3.2.5. Electrode Selection

Checkboxes for showing or hiding the following channels:

Electrode Selection checkboxes with numbered callouts grouping the EEG channels (F8, AF4, AF3, F7), the zygoma EMG channels (L Zygoma, R Zygoma), and the Cardio channel checkbox.

  1. F8, AF4, AF3, F7 (EEG)
  2. L Zygoma, R Zygoma (EMG)
  3. Cardio (ECG)

3.2.6. EEG Scale

Drop-down list for setting a fixed Y-axis scale for EEG channels (auto, 20, 50, 100 µV).

EEG Scale dropdown expanded to show the fixed Y-axis scale options auto, 20, 50, and 100 microvolts, next to the electrode selection checkboxes.
