Hello SPM'ers,
I have PET data from multiple groups (Group on Drug # 1, Group on Drug # 2 and Normals)
The 2 groups on Drugs have scans at 3 different time points (Baseline, Week 1 and Week 8; one scan per subject per time point), the Normal group has only one scan per subject.
I would like to perform these comparisons:
1. I am trying to compare the Normal scans with the Baseline scans of both on drug groups.
2. Effect of each drug: Week 8 minus Week 1, Week 8 minus baseline and Week 1 minus baseline
What first level and second level models should I use from the PET SPM2 model options.
Thanks in advance.
