ReconstDtiFlow
Workflow for tensor reconstruction and for computing DTI metrics.
using Weighted Least-Squares.
Performs a tensor reconstruction on the files by ‘globing’
input_files
and saves the DTI metrics in a directory specified by
out_dir
.
Parameters
- input_files : string
- Path to the input volumes. This path may contain wildcards to
process multiple inputs at once.
- bvalues_files : string
- Path to the bvalues files. This path may contain wildcards to use
multiple bvalues files at once.
- bvectors_files : string
- Path to the bvectors files. This path may contain wildcards to use
multiple bvectors files at once.
- mask_files : string
- Path to the input masks. This path may contain wildcards to use
multiple masks at once. (default: No mask used)
- b0_threshold : float, optional
- Threshold used to find b=0 directions (default 0.0)
- bvecs_tol : float, optional
- Threshold used to check that norm(bvec) = 1 +/- bvecs_tol
b-vectors are unit vectors (default 0.01)
- save_metrics : variable string, optional
- List of metrics to save.
Possible values: fa, ga, rgb, md, ad, rd, mode, tensor, evec, eval
(default [] (all))
- out_dir : string, optional
- Output directory (default input file directory)
- out_tensor : string, optional
- Name of the tensors volume to be saved (default ‘tensors.nii.gz’)
