Data Access

All StudyForrest data are contained in a collection of DataLad datasets hosted on GitHub, OpenNeuro, and GIN.

DataLad provides fine-grained data access down to the level of individual files, and allows for tracking future updates. It is a free and open source command line tool, available for all major operating systems, and builds upon Git and git-annex to share, synchronize, and version control collections of large files.

More information on DataLad and how to install it can be found in the DataLad Handbook.

Get the Dataset

The dataset can be cloned by running:

datalad clone https://github.com/psychoinformatics-de/studyforrest-data

Once the dataset is cloned, it is a light-weight directory on your local machine. At this point, it contains only small metadata and information on the identity of the files in the dataset, but not actual content of the (sometimes large) data files.

Retrieve Dataset Content

After cloning the dataset, you can retrieve file contents by running:

datalad get path/to/directory/or/file

This command will trigger a download of the files, directories, or subdatasets you have specified.

This dataset contains other datasets, so called subdatasets. If you clone the top-level dataset, subdatasets do not yet contain metadata and information on the identity of files, but appear to be empty directories. In order to retrieve file availability metadata in subdatasets, run:

datalad get -n path/to/subdataset

Afterwards, you can browse the retrieved metadata to find out about subdataset contents, and retrieve individual files with datalad get. If you use datalad get path/to/subdataset, all contents of the subdataset will be downloaded at once.
