fMRIprep slice time correction uses the middle slice as the reference by default, but it is possible to change this. What does fitlins assume about slice time correction, if anything?

Currently assumes bold starts at 0s. Shifting events back by the start time is necessary to model a slice timing correction shift.

Just to clarify, that means that --slice-time-ref start / --slice-time-ref 0 will have satisfy fitlin's assumptions?
