eye data scaling from TCP/IP EyeLink

Hi Jaewon,

We are recording eye-movements in ML via TCP/IP.

We calibrate in EyeLink and use the uncalibrated input.

The data is there in the BHV but on replay (in the after-task viewer) the eyemovements are very small displayed across the viewed image.

Should we be using the gain feature in the TCP/IP pop-out settings window? Our gain is now set to -0.0005

Or is there a setting on the eye-link side to scale the data that may be incorrectly set?

Sorry, when I did this with the NHPs using the Arrington systems we did not have this scaling issue.

Resolved: After getting the 2D spatial transform calibration to work correctly with our system (requires forced use of callback screen), we are getting calibrated and aligned eye-movement data.
