I am conducting an E-prime experiment that is connected with eyetracking remote system (SMI RED 500). In terms of analysis, the eyetracking analysis software (SMI, BeGaze analysis software) can only record the eye-movements but not the stimuli, so the BeGaze does not know which stimuli has been looked at. The only way to overcome this is to be able to write the stimulus id into the eye-tracking idf file in e-prime. However I do not know how to do it. I hope you can help me. By doing this, I can know which stimuli is being looked at in the BeGaze analysis referring to the stimulus id.
Thank you very much!
