Folder can be run with python 3 like so:python3 folder.py path/to/data new/empty/destination/path 5 This will create 5 folds in the second path.

You can also run it with an additional parameter, the percentage of the training set. This should be given as a number between 0 and 1. By default this is set to 0.8 (80%). The python call will then look like this: python3 folder.py path/to/data new/empty/destination/path 5 0.9

To create a unique test set, you can use uniqueFolder.py. Usage is the same as folder.py.
