I'm analyzing RSNs MRI images. I have two sets of scans, each one with the same ten people: the first scan is made before a motor task and the second one after it. I want to compare the ICs of two scans. I used MELODIC, and I know that I should use "dual regression", but I have a problem with the steps of this function. In particular, I don't know how to build a model with GLM, because in the RSN scans I haven't EV or other conditions and then I have two different design.fsf to upload in the GLM gui.
I could upload all the twenty scans together but in this way I would lose the information about ICs before and after the task. Because my aim is to characterize statistically the differencies between the RSNs before and after the experiment.
Could you please provide me with some details about the steps of this kind of analysis?
Otherwise if you have other suggestions to make, I would be glad to hear them.
I'm writing my thesis and I really need some help from exepert people.
I thank you in advance for your kind help.
