Hi AS,
You can basically do either two things:
1. estimate a model without you nuissance regressors (e.g. for residual motion efffects and others whatever they are ...): and then compare the outputs of the two models (a bit fiddly)
or (less fiddly):
2. run a model treating nuissance regressors we they were of your interest; assigning 'ones' to them and setting others to '0'; this gives an idea where actually the effects of noises map to (for movement it should be concentrated around the brain edges).
As far as I can remember these procedures are explained somwhere in the spm tutorial
Hope this helps,
Iwo

Subject: [SPM] Displaying images after correcting for noises
Dear all,
Is there any way that I can display/get functional images after correcting for movement and physiological noises. What I want is basically to compare and see the effects of them before and after correction. So for example if I add all the regressors in my GLM and count for them, I would like to extract my functional images again after these corrections. I hope I deliver my question clearly:)
Thanks in advance
AS
