Description: Preprocessed DTI scans used in the Plos One paper "Groupwise registration of infant brain diffusion tensor images using intermediate subgroup templates" Diffusion MRI data preprocessing details: Diffusion MRI data were preprocessed using FSL 5.0.9 and in-house Matlab code (Matlab 2023). Preprocessing steps included correction for eddy-current distortion and removal of susceptibility distortion using the eddy and topup functions in FSL. Tensor maps and tensor-derived scalar maps, including maps of fractional anisotropy (FA) and mean diffusivity (MD), were calculated using FSL’s function dtifit with weighted least-square tensor fitting. Weighted least-square fitting was used to minimize the impact of motion on the infant data.
