Create a folders with symbolic links to all cast volumes

In the following script we create a folder containing symbolic links to all casted volumes

Warning

this is the ‘cast volume’ output that must be connected to the Python script ‘volume’ input.

Script

import os
from tomoscan.esrf.volume.singleframebase import VolumeSingleFrameBase

output_dir = "/path/to/folder" # root folder of the symbolic links

if in_volume is not None:
    link_src = in_volume.data_url.file_path()

    link_dst = os.path.join(
        output_dir,
        in_volume.get_identifier().scheme, # optional: if you want to store your data with under output_dir/j2k, hdf5... Can be useful if you have more than one output data type
        os.path.basename(link_src),
    )
    target_is_directory = isinstance(in_volume, VolumeSingleFrameBase)
    os.makedirs(os.path.dirname(link_dst), exist_ok=True)

    os.symlink(link_src, link_dst, target_is_directory=target_is_directory)
