SPM HPF at first level for task data

Hey folks,

I've reading some suggestions for how to use conn preprocessed and scrubbed data in SPM, task-based activation analyses. Our task data was processed and denoised in conn (to reflect the default filter in SPM). I understand it is suggested when making spm first level models to set the masking threshold to -inf when using the d*.nii images from CONN, but what is the recommended hpf for the first level models as well? Would this also be -inf or inf becuase the data have been filtered already?
