3.2. Controls

3.2.1. General Settings #

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

3.2.2. Signal Processing 1 (upper graph, green) #

3. Type: RAW / Filtered (if no value is selected for signal 2, signal 2 is not shown)
4. CAR: Common average reference
5. Denoise: Blink artifact suppression
6. IMF: EMD mode selection
7. Filter: Frequency filter selection
8. 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 #

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:

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).
