Dear SPM experts,
I'm running a DCM 2nd level analysis to 3 groups (6 subjects). In order to found differences
between them, I'm following the steps:
- All subjects' DCMs are in a GCM file
- In the batch, I choose: DCM -> second level -> Specify/estimate PEB
In Covariates, I have specified a vector to see group1>group2: 1 1 -1 -1 0 0
In this context, are Covariates appropriate to do this contrast?
Then, I run DCM -> second level -> Search nested PEB models.
Is it rigth, please?
thanks a lot.
Helka
