Hi,
I want to construct a first-level GLM in FEAT. My interest focuses on a 6 s decision period. Subjects either correctly or incorrectly made a decision in each trial. I want to model 2 EVs (using 3-column format txt file) for this period, i.e., correct-trial EV and incorrect-trial EV, and make comparisons at the group level. However, I notice that some subjects have done all trials correctly. Can I still use a blank txt file for the incorrect-trial EV in these subjects?
Thanks.
Mike
