Longitudinal design - 2 timepoints 2 runs
Hi list,

I have a longitudinal design with 2 timepoints and 2 runs each one. 
In addition, a design 2x2 for between subject analysis.
For within subject contrast, I have inserted 4 sessions and multiple anatomical images:

S1 -- timepoint1 and run1 + Anatomical images at timepoint1 
S2 -- timepoint1 and run2 + Anatomical images at timepoint1
S3 -- timepoint2 and run1 + Anatomical images at timepoint2
S3 -- timepoint2 and run1 + Anatomical images at timepoint2

In this way, how can I definite the contrast (-1, 1) for timepoint1 and timepoint2.
Now I have 4 blocks (S1, S2, S3, S4).

Thanks

Stefano
