Hi,
I am making an analysis in freesurfer 5.1 using mkanalysis-sess and I am a bit confused about the flag refeventdur. In the help it is said that it should be set to the event duration if the events have similar durations. But I have two conditions with different durations that one lasts for 1.6 second and another lasts 0.8s in a event-related design paradigm, and my fixation condition lasts for 8 second. What should I set the refeventdur to? How does this value influence the design matrix?
Thanks, WangHan
