Jeremy, I have one more question.
It is about the fixation duration.
In the data attached above,
trial time left right
11 1920 0 1
11 2087 0 0
11 2250 1 0
11 2416 1 0
11 2581 1 0
11 2751 0 0
The fixation duration of (left, right) = (0,1) is 2087-1920. is it right?
Then, how can I calculate the last fixation (time = 2751)?
always thanks!
