Hi @olibclarke is the dataset you are referring to (2.7A → 2.2A) the same that you mentioned here: Use patch based motion correction as prior for local motion correction? - #5 by olibclarke ?
You are correct that it is worth re-doing motion correction for datasets originally processed between Dec 2020 and March 2021 (or on versions v3.0 and v3.1).
