Hi Anderson,
Thank you so much for your response! I would like to clarify 3 things:
1. I have 327 runs from 172 subjects. Some subjects have 1 run-worth of data and some have 2. It seems wrong to simply code each run separately, since runs from the same subject are not truly independent. Can we represent the fact that some runs come from the same subject? Or should we have just the 4 evs, as you suggest?
2. These data came from 3 different studies that we are combining. We are currently using a continuous variable to represent the study that the data comes from. Is that problematic?
3. I am afraid that we are likely to introduce human error by putting 172 subjects into the GUI by hand. Why is it better to use the GUI? (Currently we are creating the matrix using a script and then using Text2Vest to convert the matrix into the proper format.)
Thanks again!!
Alex
