Hello,

I am wondering how to implement a paired t-test in 3dMema.

I have a dataset wherein participants are exposed to the same stimulus during two different tasks (taskA and taskB). 10 Participants perform taskA in run 1 and taskB in run 2. During each run they are exposed to six 30 second blocks of the stimulus.

For the first level analysis I have modeled the runs separately (as the baseline conditions in each run are different) using 3Ddeconvolve and 3DReml fit. I would now like to use 3dMEMA to examine the effects of the stimulus in TaskA vs TaskB.

Would it be correct to compute the differences between the betas in Task A and Task B for each participant from the stats.reml output and use these as input for 3dMEMA? If this is case, how would I compute the within-subject variability for the input?

Thanks and Cheers,
Gerome
