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] [–nbr_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 (default 6) 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 (default 8)
- --b0_threshold float
Threshold used to find b=0 directions
- --bvecs_tol float
Threshold used so that norm(bvec)=1 (default 0.01)
- --extract_pam_values
Wheter or not to save pam volumes as single nifti files.
- --parallel
Whether to use parallelization in peak-finding during the calibration procedure. Default: False
- --nbr_processes int
If parallel is True, the number of subprocesses to use (default multiprocessing.cpu_count()).
- output arguments(optional):
- --out_dir str
Output directory (default input file directory)
- --out_pam str
Name of the peaks volume to be saved (default ‘peaks.pam5’)
- --out_shm str
Name of the spherical harmonics volume to be saved (default ‘shm.nii.gz’)
- --out_peaks_dir str
Name of the peaks directions volume to be saved (default ‘peaks_dirs.nii.gz’)
- --out_peaks_values str
Name of the peaks values volume to be saved (default ‘peaks_values.nii.gz’)
- --out_peaks_indices str
Name of the peaks indices volume to be saved (default ‘peaks_indices.nii.gz’)
- --out_gfa str
Name of the generalized FA volume to be saved (default ‘gfa.nii.gz’)
