fMRIprep BOLD reference image same across sessions?

It’s unclear to me from the fMRIprep documentation whether the BOLD reference image used for motion correction is created within or across sessions. Basically, I have two sessions, each containing multiple runs, and I want to have all runs from both sessions aligned to one single reference image. Is this automatically done with fMRIprep or if not, is this an option?


Hi, the BOLD reference is created within run, meaning that there is no common reference for all runs in a session nor a common reference across sessions.

It is not automatically done with fMRIPrep and at this point it is not an option. There are two related issues in our repo:
