Hi Alfonso,
great, thanks again!

Yes, exactly.
Selecting the "effect of X" source will compute the association
between that covariate and the BOLD signal within each target
voxel/ROI, which is equivalent to a classical GLM where the design
matrix includes the "effect of X" covariate (so you are testing the
"activation" of your target voxel/ROI in response to your
condition)
Hope this helps

Hi Alfonso,
thank you very much for your helpful reply. I will follow your suggestion and include the conditions as Confounds.
Just to make sure I understand: if I do _not_ do this, the "effect of X" item which is included in the list of 'sources' would correspond to a ROI defined by the "activation" of the BOLD signal in response to the effect of X, as determined by a classical GLM?
Thanks again
Nicola
