dipy_gibbs_ringing

Usage

dipy_gibbs_ringing [-h] [–slice_axis int] [–n_points int]

[–num_processes int] [–out_dir str] [–out_unring str] input_files

Workflow for applying Gibbs Ringing method.

Positional Arguments

input_files Path to the input volumes. This path may contain wildcards to process multiple inputs at once.

Optional Arguments

-h, --help

show this help message and exit

--slice_axis int

Data axis corresponding to the number of acquired slices. Could be (0, 1, or 2): for example, a value of 2 would mean the third axis.

--n_points int

Number of neighbour points to access local TV (see note).

--num_processes int

Split the calculation to a pool of children processes. Only applies to 3D or 4D data arrays. Default is 1. 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_unring str

Name of the resulting denoised volume.
