Hi - the FEAT preprocessing happens in the order that it appears in the GUI Pre-Stats section, top-to-bottom: motion correction happens first. In general it is better to correct for motion before doing slice timing correction, but then in general we don't recommend doing slice- timing correction. Cheers.
