dipy_fit_csa

Usage

dipy_fit_csa [-h] [–sh_order int] [–odf_to_sh_order int] [–b0_threshold float] [–bvecs_tol float] [–extract_pam_values] [–parallel] [–num_processes int]

[–out_dir str] [–out_pam str] [–out_shm str] [–out_peaks_dir str] [–out_peaks_values str] [–out_peaks_indices str] [–out_gfa str] input_files bvalues_files bvectors_files mask_files

Constant Solid Angle.

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 bvectors files. This path may contain wildcards to use multiple bvectors 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

--sh_order int

Spherical harmonics order used in the CSA fit.

--odf_to_sh_order int

Spherical harmonics order used for peak_from_model to compress the ODF to spherical harmonics coefficients.

--b0_threshold float

Threshold used to find b0 volumes.

--bvecs_tol float

Threshold used so that norm(bvec)=1.

--extract_pam_values

Whether or not to save pam volumes as single nifti files.

--parallel

Whether to use parallelization in peak-finding during the calibration procedure.

--num_processes int

If parallel is True, the number of subprocesses to use (default multiprocessing.cpu_count()). If < 0 the maximal number of cores minus num_processes + 1 is used (enter -1 to use as many cores as possible). 0 raises an error.

Output Arguments(Optional)

--out_dir str

Output directory. (default current directory)

--out_pam str

Name of the peaks volume to be saved.

--out_shm str

Name of the spherical harmonics volume to be saved.

--out_peaks_dir str

Name of the peaks directions volume to be saved.

--out_peaks_values str

Name of the peaks values volume to be saved.

--out_peaks_indices str

Name of the peaks indices volume to be saved.

--out_gfa str

Name of the generalized FA volume to be saved.
