Test dataset for RABIES

This is a test dataset for testing the installation of RABIES (https://github.com/CoBrALab/RABIES). The dataset contains structural and functional scans from 2 mouse subjects. The workflow should run with the default parameters by running "rabies preprocess test_dataset/ output_folder/". The speed of testing can be increased by specifying lower anatomical resolution (i.e. --anatomical_resampling 0.4x0.4x0.4), and the workflow should still run completely, but the quality of the preprocessing will be impaired.
