Dear SPMers,
My question is about a 1 group fMRI study where whe want to assess, at
the second level, the effect of one contrast previously evaluated at the
individual level, but adjusted for a specific covariate.
In SPM2, we can choose an ANCOVA model, 1 group and 1 nuisance variable.
it results a SPM.mat with two columns: 1 for a constant term and 1 for
the nuisance variable.
Is this design valid for what we want to do?
Is the contrast [1 0] effectively test our effect adjusted for the
nuisance variable?
thanks for your help
Jerome
