Dear SPMers,
I have data from two tasks assigned to different runs. I would like to compare, say, condition 1 of task 1 (runs 1,3,5,7) and condition 1 of task 2 (runs 2,4,6,8). I would appreciate your suggestions for the following questions:
1. Can i put the two tasks in one design matrix?
2. Can i make a comparison between conditions adding a run as a covariate?
3. What is general disadvantage of such comparison?
thank you in advance
alla
