Hi,
I'm using spm8 toolbox for analyzing rest fmri data. I want to remove DC artifact from my data which is meant to be done by adding a DC regressor to the design matrix but I don't know how to do it as in the spm 1st level analysis batch editor menu there's no option for that! I think I have to add that to the fmri-Design.m file included in spm directory but I don't know how to as my knowledge of matlab programming is not good and I mainly take advantage of GUI using spm.
I will appreciate it if someone can help me out with this
regards
Mary
