I was wondering if any of you know of an atlas for the newer MNI template used in fMRIPREP as the default (MNI152NLin2009cAsym), or a way to somehow transform coordinates from this template to the sixth-gen MNI that is used everywhere.
Please not that SPM and FSL use different variants of the MNI template. Additionally depending which processing stream you use in SPM different templates are used. However, considering the spatial resolution of most fMRI data, I would be surprised if there was much of a difference in the results transformed between different templates.
