DATASET DESCRIPTION

This page serves the Brain/MINDS age-specific marmoset averaged image dataset for downloading. The dataset includes gunziped 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” bellow. 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 Mrtrix3’s command:
# mrconvert dwi_input.mif dwi_output.nii -export_grad_fsl bvec bval

Files can be downloaded each image type or as one zip file.
