========================

usage: dipy_info [-h] [--b0_threshold float] [--bvecs_tol float]
                     [--bshell_thr float]
                     input_files [input_files ...]

Provides useful information about different files used in medical imaging. Any number of input files can be provided. The program identifies the type of file by its extension.

positional arguments:
  input_files           Any number of Nifti1, bvals or bvecs files.

optional arguments:
  -h, --help            show this help message and exit
  --b0_threshold float  (default 50)
  --bvecs_tol float     Threshold used to check that norm(bvec) = 1 +/- bvecs_tol b-vectors are unit vectors (default 0.01)
  --bshell_thr float    Threshold for distinguishing b-values in different shells (default 100)
