variable "experiment" has 2 channels

1: LSL time stamps
2: experiment code:

-99: experiment starts
for the first experiment the next four elements are repeating:
first element: trial ID (0-17), start of trial (trial lasted 2.5 seconds)
second element: nback level (0-3)
third element: displayed stimulus of trial (0-9)
fourth element: participant response (0 target, 1 non-target, -1 no response)

for the second experiment the next four elements are repeating:
first element: trial ID (0-17), start of trial (trial lasted 5 (display exercise) + 3.5 (participant response) = 8.5 seconds)
second element: first number to be added (1-875)
third element: second number to be added (1-875)
fourth element: participant response (number or -1 if no response)
