dipy_nlmeans
========================

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

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)
