Dear FSL Experts,
Hi,
I am using FEAT to do seed-based functional connectivity analysis. I need to add some confounds to my GLM. Because of the large number of confound regressors that I have, I need to use "Add additional confound EVs" option in "Stats" tab.
1) I am wondering if my regressor of interest defined in the "Full model setup" (i.e. the averaged time course over ROI) will be automatically orthogonalized with respect to these confounds (I know that there is an option to orthogonalize regressors defined in "Full model setup" wrt. each other, but what about the EVs wrt. confounds?).
2) If not, how can I change the source code to be able to do so?
Thanks in advance and looking forward to hearing from you,
Mona
