Hi Rick,
Thank you so much for the thoughtful comments. These really help. I'll pre-process each run separately. I only ran 3dTcat so that should be the original dimension?
Could you please clarify one more thing? After running the preprocessing separately, would it make sense to include each into the group analysis? For example in the 3dttest++, would the below be possible?
-setA ConditionA
Subj1_REST1LR /subject1_REST1LR
Subj1_REST1RL /subject1_REST1RL
Subj1_REST2LR /subject1_REST2LR
Subj1_REST2RL /subject1_REST2RL

-setB ConditionB
Subj1_REST1LR /subject1_REST1LR
Subj1_REST1RL /subject1_REST1RL
Subj1_REST2LR /subject1_REST2LR
Subj1_REST2RL /subject1_REST2RL
Best,
JW
