FMRIPrep Preprocessed T1-weighted Image

FMRIPrep produces a preprocessed version of the T1-weighted image stored in the ‘anat’ folder with the pattern ‘sub*_desc-preproc_T1w.nii.gz’.

  1. Do you think using this preprocessed image is preferred for voxel-based morphometry (VBM) instead of using the initial non-preprocessed T1-weighted image?

  2. What preprocessing steps have been performed to this image?

Hi @mras,

Yes. You may also consider a surface based morphometry study instead with your freesurfer outputs, which enable cortical thickness and surface area estimations, in addition to volume.


You can also read the methods boilerplate in the html for a description of steps with citations.

Best,
Steven
