======================== 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') References: ..
