I want to use 3dTRfix to resample cardiac-gated fMRI data to uniform time intervals. 3dTRfix says resampling will include the effects of slice time offsets if they are stored in input dataset’s header. I believe this is to correct for slice timing difference between slices.
I used custom-made acquisition sequence to collect my data. My question is: which header field does 3dTRfix use for this time offset? I don’t know if it is saved in my header. If it isn’t, perhaps it can modify the header to include it.
I’m new to afni.
