Generates a fully separable dataset.
Generates a dataset, based on the images of the CAPS directory, where a

Args:

output_dir: (str) folder containing the synthetic dataset in CAPS format.
n_subjects: (int) number of subjects in each class of the synthetic
dataset.
tsv_path: (str) path to tsv file of list of subjects/sessions.
preprocessing: (str) preprocessing performed. Must be in ['linear', 'extensive'].
mask_path: (str) path to the extracted masks to generate the two labels.
atrophy_percent: (float) percentage of atrophy applied.
multi_cohort (bool): If True caps_directory is the path to a TSV file linking cohort names and paths.
Returns:
Folder structure where images are stored in CAPS format.
