Anatomical-to-mni transformation not the same as in fmriprep folder

1

I’m trying to replicate the anatomical-to-MNI transformation using antsApplyTransforms on fmriprep output:

antsApplyTransforms -d 3 --float 1 -i sub-01_desc-preproc_T1w.nii.gz -o T1w-to-MNI.nii.gz -r MNI152_T1_1mm.nii.gz -t sub-01_from-T1w_to-MNI152NLin6Asym_mode-image_xfm.h5

but the output image is not exactly the same as fmriprep’s sub-01_space-MNI152NLin6Asym_desc-preproc_T1w.nii.gz.

Are there any options missing in my command?

Thanks!
