Dear Smith,
I just want to let high pass filter not work when using melodic. I had thought I might make it by seting a cutoff point longer than the duration of a fMRI experiment.
But from your reply, it seems for a cutoff point longer than the known experimental paradigm period, the high pass filter still works. So whether I can using a command line function to avoid high pass filtering?
Regards,

I'm not quite sure what you're asking, but if you want to exclude
effects slower than the known experimental paradigm period, just set
that value in the appropriate part of the GUI.
Cheers.
