Can I get the pupil size when running my experiment with E-prime?

Tobii Pro Studio E-Prime Extensions Tobii Pro

When running an experiment with E-prime, the E-prime Extension for Tobii, and a compatible Tobii Pro eye tracker, DiameterPupilLeftEye and DiameterPupilRightEye can be retrieved in the E-prime .gazedata file.

When using a dual setup with both E-prime and Tobii Studio, the pupil size can also be retrieved from the Data Export tab in Tobii Studio.
