Performs a DKI reconstruction on the files by 'globing' ``input_files`` and saves the DKI metrics in a directory specified by ``out_dir``. positional arguments: input_files Path to the input volumes. This path may contain wildcards to process multiple inputs at once. bvalues_files Path to the bvalues files. This path may contain wildcards to use multiple bvalues files at once. bvectors_files Path to the bvalues files. This path may contain wildcards to use multiple bvalues files at once. mask_files Path to the input masks. This path may contain wildcards to use multiple masks at once. (default: No mask used) optional arguments: -h, --help show this help message and exit --b0_threshold float Threshold used to find b=0 directions (default 0.0) --save_metrics [str [str ...]] List of metrics to save. Possible values: fa, ga, rgb, md, ad, rd, mode, tensor, evec, eval (default [] (all)) output arguments(optional): --out_dir str Output directory (default input file directory) --out_dt_tensor str Name of the tensors volume to be saved (default: 'dti_tensors.nii.gz') --out_fa str Name of the tensors volume to be saved (default 'dki_tensors.nii.gz') --out_ga str Name of the fractional anisotropy volume to be saved (default 'fa.nii.gz') --out_rgb str Name of the geodesic anisotropy volume to be saved (default 'ga.nii.gz') --out_md str Name of the color fa volume to be saved (default 'rgb.nii.gz') --out_ad str Name of the mean diffusivity volume to be saved (default 'md.nii.gz') --out_rd str Name of the axial diffusivity volume to be saved (default 'ad.nii.gz') --out_mode str Name of the radial diffusivity volume to be saved (default 'rd.nii.gz') --out_evec str Name of the mode volume to be saved (default 'mode.nii.gz') --out_eval str Name of the eigenvectors volume to be saved (default 'evecs.nii.gz') --out_dk_tensor str Name of the eigenvalues to be saved (default 'evals.nii.gz') --out_mk str Name of the mean kurtosis to be saved (default: 'mk.nii.gz') --out_ak str Name of the axial kurtosis to be saved (default: 'ak.nii.gz') --out_rk str Name of the radial kurtosis to be saved (default: 'rk.nii.gz') References: ..
