HD EEG Timing Test

1. Make sure the Stimulus and Acquisition computers have both been turned on and the photodiode is flush with the center of the Stimulus computer screen before starting. 

    (Steps done on the Acquisition computer start with "A:" and steps done on the Stimulus computer start with "S:")

2. A: Open "Netstation Acquisition"

3. A: Make sure "Sampling Rate" is 1000 s/s

4. A: Make sure "Din Events" is 255 Dins

5. A: Click "on"

6. S: Start IO_test in MatLab (set parameters such as number of repetitions and between trial pause)

7. A: Press record button (red circle) when Stimulus computer screen is sitting at an unchanging black.

8. S: Press any key.

9. A: When flickering stops, press stop button (black square).

Method 1:

10. A: Open "Event Timing Tester"

11. A: Open the file you just created.

12. A: Set "Stim Event Code" to: DIN3

13. A: Set "DIN Event Code" to: DIN2

14. A: Click "Create Timing Table"

15. A: Observer results (in ms)

Method 2:

10. A: Open "Net Station Review"

11. A: Open/Drag in file you just made

12. A: Click "Event View" button (fifth icon from the left on the bottom of the window).

13. A: Make sure you have 3 separate Dins and it goes: Din 2 -> Din 3 -> Din 1

14. A: If everything looks ok, close "Netstation Acquisition"

15. A: Open "Netstation Tools"

16. A: Drag file to "Input Files"

17. A: Go to "All Tools"

18. A: Highlight "timing_test_export"

19. A: Click "Run"

20. A: Find the .evt file and transfer it to a computer with MatLab

21. Resave the .evt file as a .txt file with a less cumbersome name.

22. Open the file named "timing_test_netstation.m" (see below)

23. Replace the filename under "fileID=fopen" with the name of your .txt file

24. Run the program

25. Look at the results
