Eprime output with eye tracking help

[grighi]

Thank you for the replies.

Unfortunately the information is very scarce and the format of the
coordinates differs between experiments run using Tobii Studio (the
eye tracking proprietary software) and Eprime with the extensions.
While the tobii studio ones are expressed in pixels values, the eprime
ones are express like 0.5557 and so on.

thanks
giulia
