Dear List,
I just tried to specify a 1st stage model on 1 subject containing a user
specified regressor only (what I want to model is not included in the
standard basis sets). SPM2 comes up with an error box saying I can't build a
model containing only user specified regressors. Is there a good reason for
this? I could of course specify one nonsense condition with only 1 event or
so, but theoretically that doesn't make much sense.
I also could of course try and put my custom made matrix in SPM.xX.X, but I am
not sure whether the other missing fields in SMP.xX would lead to errors.
Thanks in advance for any insights,
Bas
