DATASET DESCRIPTION

The dataset includes gziped NIfTI files (.nii.gz) of MRI T2WI and DTI metrics (FA, MD, RD, and AD) in-vivo data; the ages of the data are 1,3,6,9,12,15,18 months old.

The creation process of these averaged images is referred to the script of FSL software (https://fsl.fmrib.ox.ac.uk/), fslvm_2_template, partially modified; the non-linear registration process was replaced to the script of ANTs (http://stnava.github.io/ANTs/), antsRegsitrationSyN.sh. The details are described in the text “Dataset Description and Image Processing”.

In addition, age-specific DWI templates (.mif files) are provided, which are created using the script of Mrtrix3 (http://www.mrtrix.org/), population_template.
You may convert .mif file to NIFTI, extracting b-vector and b-value information by conducting the following Mrtrix3s command:

# mrconvert dwi_input.mif dwi_output.nii -export_grad_fsl bvec bval
