Hi - I'm doing a first-level analysis of fMRI data in SPM, and want to use realignment parameters (rp text file in the preprocessing folder) as additional regressors (ie select the rp file as "Multiple regressor").
However, I've already done normalization in FSL (using nonlinear registration).
Can I input the already normalized 4D functional to SPM, and run realignment on this in SPM, to get that rp text file that I can later input as a regressor?
I understand that in SPM, the procedure is usually to do realignment (followed by coregistration, segmentation), and only then normalization.
Thanks,
Joelle
