Source code for unravel.image_io.metadata

#!/usr/bin/env python3

"""
Use ``io_metadata`` from UNRAVEL to save x/y and z voxel sizes in microns as well as image dimensions to a metadata file in each sample directory.

Inputs:
    - .czi, .nii.gz, .h5, or TIF series (path should be relative to ./sample??)

Outputs:
    - ./parameters/metadata.txt (path should be relative to ./sample??)

Note:
    - If -d is not provided, the current directory is used to search for sample?? dirs to process. 
    - If the current dir is a sample?? dir, it will be processed.
    - If -d is provided, the specified dirs and/or dirs containing sample?? dirs will be processed.
    - If -p is not provided, the default pattern for dirs to process is 'sample??'.
    - To test out -d/-p, use the ``utils_get_samples`` command to see which sample?? dirs will be processed.

Next command:
    - ``reg_prep`` for prepping autofluo images for registration

Usage for when metadata is extractable:
---------------------------------------
    io_metadata -i rel_path/full_res_img [-m parameters/metadata.txt] [-d space-separated list of paths] [-p pattern] [-v]

Usage for when metadata is not extractable:
-------------------------------------------
    io_metadata -i tif_dir -x 3.5232 -z 6 [-m parameters/metadata.txt] [-d space-separated list of paths] [-p pattern] [-v]
