     The following preprocessing steps are required.
     1. Skull-stripping using [SynthStrip](https://surfer.nmr.mgh.harvard.edu/docs/synthstrip/) with the `--no-csf` flag for optimal results.
     2. N4 bias field correction using [ANTs](https://github.com/ANTsX/ANTs/wiki/N4BiasFieldCorrection).
     3. Affine registration to the MNI 1mm isotropic template space.

+    BrainAgeNeXt has been trained and validated using over 11,000 T1w MRI acquired at 1.5, 3, and 7T. A 1mm isotropic resolution of the input image is preferred, but not required.
