1. The first step is to select a record and click on "Timeseries".


Then select "Toolbox"

Step 1 image

2. Profile allows you to store a configuration for later use, including tags and labels

3. To add a nex profile, select "+"

Step 3 image

4. Enter a name, then click on Save icon

Step 4 image

5. To select the specific signals you need, Click Select signals

Step 5 image

6. You can drag any signal (each has their own box) from ‘available’ to ‘selected’ to view it in the viewer. You can also drag the box up and down to change its viewing location in the viewer.

7. Press ‘multiplot’ at the bottom right to implement your desired workspace / montage and to plot the selected signals on the y-axis. Then click Close

8. If too many channels are displayed, you can always quickly hide some using the quick command

Step 8 image

9. The ‘Scale config’ is very useful to change the size of the signal, i.e. to change y-axis on particular data. To auto-adapt the scale, you can also press F

Step 9 image

10. Adjust scale settings as desired. You may want to adjust the EEG scale to -60 ; 60 to see more detailed tracings. Click ‘Apply to Domain’ to apply scales to all signals in the same domain.

Step 10 image

11. To export the signal of a particular window/epoch with a SVG format, select "Export as SVG" .

Step 11 image

12. Limiter allows you to cut the signal for a better visibility.

Step 12 image

13. Reference lines allows you to set dotted lines that can be taken as a reference to show you when you meet certain amplitude criteria for certain signals.

Step 13 image

14. For instance you might want to set a reference line between +50 and -50 uV on Channel 1

Step 14 image

15. The"Zoom" feature is meant to change the size of the window and the definition of the EEG you are looking at.

Step 15 image

16. Click Hypnogram. It allows you to select different hypnograms.

Step 16 image

17. If selected, sleep stage for every epoch will be extracted and plotted on top of signal visualizer.

Step 17 image

18. Click FFT to get the spectral analysis of each channel, the frequency of specific channels at certain times.

Step 18 image

19. Scroll down and click Stimulations. 
It will display stimulations emitted during N3.
