Hi Jason,
we are using this model both for VBM (Dartel) and fMRI data.
With fMRI we run a Condition B - Condition A contrast from the first level individual subject analyses and they are the images we use in the 2nd level analysis.
With VBM we use individual subjects' grey matter images, so I guess it means there is only one level of analysis.
But we'd like to run the same analyses on both types of data if possible.
'Developmental level' is in the model as an age (in months) covariate. So we have both the testing time/round and age at testing in the model. Does this make sense? (and is it correct?!).
