Hello,
I have a block task-based design where each subject performed the same 9 tasks during two seperate fMRI scans within the same session visit. However, the two scans are counter-balanced and have a different order of tasks performed.
For example:
1st scan task order: A-B-C-C-B-A-A-C-B
2nd scan task order: C-B-A-A-B-C-C-A-B
How would I specify two different sets of timing files for a symbolic specification of the model in the -regress_opts_3dD section of the afni_proc.py script?
Or would it be easier and still appropriate to concatenate the scans?
