     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 is preferred for the input image but not required. Our [manuscript](https://doi.org/10.1162/imag_a_00487) presents a detailed explanation of **BrainAgeNeXt** and its potential applications.
