Dose two output resolution of one template double the processing time?

I try to process my data with parameters : T1 image in 1mm and fMRI image in 2mm. However, I found that there is probably no such option in fMRIPrep, so I set the output space as --output-spaces MNI152Lin:res-1:res-2.
I’d like to konw will fmriprep run the same processing twice for the two resolutions so that double the time?

The resampling is at the end of the process. So the only step in the pipeline that will take longer is the final resampling(s), so adding another resolution will not double the processing time.


Thanks for your reply! :grinning: :grinning:
