Eprime output with eye tracking help

[Ashtyster]

Well, I've never used E-Prime's output to look at the eye data. So I
have no idea what it looks like.

But why do you need to look at E-Prime output anyway, if you use Tobii
Studio (which allows you not only to get eye coordinates, but also
analyze eye data)?
