I just wanted to mention two developments regarding this issue:
-
fMRIPrep now allows you to generate derivatives exactly matching templates other than MNI152NLin2009cAsym. That is using the new
--output-spacesargument. For instance:--output-spaces MNI152NLin6Asym:res-2will give you preprocessed fMRI with the grid of the FSL MNI template (i.e., 2mm isotropic resolution and 91x109x91 matrix size). -
TemplateFlow now includes the harvard-oxford template resampled to the default template of fMRIPrep (MNI152NLin2009cAsym).
