Hi Experts,
I am processing my subjects resting fmri data in MELODIC temporal concat mode. As I have only experience with resting data, I am not used to setting up the EV/model.
I basically have about 20 subjects divided amoungst 3 groups (normal, autism, other developmental delay).
The Post Stats gives the options for files below, which I assume would take on the following values/inputs:
- Time series model: none
- Time series contrasts: none
- Session/subject model:
EV1 EV2 EV3
sub 1 0 0 1
sub 2 0 1 0
..
..
sub 20 1 0 0
where EVs are the group (normal, autism, other) 0 = don't belong to that group; 1 = do belong
If so, can I make this from a plain text file, or how can it be done using FEATs Model Set Up Wizard?
- Session/subjects contrasts:
EV1 EV2 EV3
sub 1 0 1 1
sub 2...
where EVs are contrasts between subjects such as sex (EV 1 = male, EV 2 = female, EV 3 = genetic abnormality)?
Am I on the right track?
Thanks for you help,
Varina
