 The classified directory (`classified_dir`) is the input directory to PyALFE and should be organized by accessions (or session ids). Inside the directory for each accession there should be a directory for each available modality.
 Here is an example that follow ALFE default structure:
-
-```
-my_mri_data
-│
-│───anat
-│   │───sub-123_T1w.nii.gz
-│   │───sub-123_T2w.nii.gz
-│   └───sub-123_FLAIR.nii.gz

-│───swi
-│    └───sub-123_swi.nii.gz
-└───perf
-     └───sub-123_cbf.nii.gz
-
-```
-To use this directory the user should provide `path/to/my_mri_data` as the classified directory. This config value can be overwritten when calling `pyalfe run` via `-cd` or `--classified-dir` option.
