usage: dipy_nlmeans [-h] [–sigma float] [–out_dir str] [–out_denoised str]


Workflow wrapping the nlmeans denoising method.

It applies nlmeans denoise on each file found by ‘globing’ input_files and saves the results in a directory specified by out_dir.

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

--sigma float

Sigma parameter to pass to the nlmeans algorithm (default: auto estimation).

output arguments(optional):
--out_dir str

Output directory (default input file directory)

--out_denoised str

Name of the resulting denoised volume (default: dwi_nlmeans.nii.gz)
