Hi guys,
I am confused about how to process the fMRI data which constitutes of multiple sessions. There were 20 subjects included in my recent experiment, each who should be test with 2 sessions (about 40mins). In practice, in order to minimize the influence of the movement of the subjects, half of them (10 subjects), were divided into 4 sessions for measuring while underwent the same task. The obtained fMRI data were analyzed with a software spm8. My first concern is can we regard the data of four sessions as a whole and merge them into one folder before analyzing?
The second problem is about the parameter setting for data acquisition. Considering the fixed durations applied, typically needs 4 scans lasting 8 seconds for each measurement, my experiment protocol is strictly not an event-design. For this reason, should I perform the analysis with 0 or 4 scans?
Please kindly let me known if you had any comments.
Best,
Jiewen
