Eprime output with eye tracking help

[Ashtyster]

Hi Giulia,

I've worked with eye-tracking for quite a bit of time. A gaze data
file should contain X and Y values (in pixel locations) for both the
pupil and corneal reflection.
You can check the documentation that came with eye-tracking software
for further reference. It's eye-tracking software that creates the dat
file with gaze info, not E-Prime.

Good luck!
