The released data are hosted at multiple locations and multiple access methods are supported.
All data files are directly accessible via any web-browser. This type of access is best for a quick perusal of the data and for downloading fewer than a lot of files.Browse Datasets
The simplest way to dowload complete data releases is to obtain data archives (tarballs) from OpenfMRI. At present, OpenfMRI hosts the following datasets:
- A high-resolution 7-Tesla fMRI dataset from complex natural stimulation with an audio movie
- High-resolution 7-Tesla fMRI data on the perception of musical genres
- Multi-resolution 7-Tesla fMRI data on the representation of visual orientation
- Simultaneous fMRI/eye-tracking while watching a movie, plus visual localizers
For details on these datasets and further instructions, please visit the respective pages on OpenfMRI.org.
For users requiring more flexibility, rsync-based data access is provided too. Available datasets can be listed via:
rsync to obtain a dataset, it is recommended to use the
-a/--archive flags. For example:
rsync -aL psydata.ovgu.de::studyforrest/phase2 dest
While users running cloud-based analysis can also use any of the methods above, please note that all datasets are also available on Amazon's S3 cloud storage. This should be the preferred data source if you are working in their cloud (e.g. with NITRC-CE). The bucket names employ the following pattern:
If you consider all of the above mediocre, then this is the option for you. git-annex offers highly flexible data access with built-in versioning and enables both tracking the complete evolution of these datasets and the obtaining of any future updates. This access method allows for complete meta-data access in combination with full or partial data download. Additional data portions can be obtained at any point in the future. Previous versions of data files are also accessible.
All data repositories for this method are publicly available on GitHub (no account is required).
Obtain the meta-data repository:
git clone https://github.com/psychoinformatics-de/studyforrest-data-phase2.git phase2
Enter the directory and initialize:
cd phase2 git annex init
Download (selected) data files — repeat as necessary. Example: all BOLD time series for the movie acquisition:
git annex get sub*/ses-movie/func/*bold.nii.gz
