We’ve used fmriprep 1.0.11 with the following flags.
–template MNI152NLin2009cAsym
–template-resampling-grid 2mm
–output-space template
We’re finding that the bold files *_bold_space-MNI152NLin2009cAsym_preproc.nii.gz have resolution 97x115x97, with 2mm isotropic voxels, but the anatomical *_T1w_space-MNI152NLin2009cAsym_preproc.nii.gz is 193x229x193, with 1mm voxels.
Obviously, this makes overlaying any first-level analysis images on the subject’s anatomical a bit annoying, if you’re using a program like fslview that wants the two images to have the same dimensions (freeview works fine, though).
Is this behavior a bug, or working as intended?
Thanks!
