An Extension of studyforrest.org Dataset

PDDL-licensed No registration or authentication required DOI

Multi-resolution 7T fMRI data on the representation of visual orientation

This dataset consists of empirical ultra high-field fMRI data recorded at four spatial resolutions (0.8 mm, 1.4 mm, 2 mm, and 3 mm isotropic voxel size) for orientation decoding in visual cortex — in order to test hypotheses on the strength and spatial scale of orientation discriminating signals. This is an extension of the studyforrest project. All seven participants previously volunteered for the audio-only and the audio-visual Forrest Gump study. The dataset is compliant with the BIDS data description standard (http://bids.neuroimaging.io). A detailed description can be found in:

Sengupta, A., Yakupov, R., Speck, O., Pollmann, S., Hanke, M. Ultra High-Field (7 Tesla) multi-resolution fMRI data on the representation of visual orientation. Data in Brief (submitted)

How to obtain the data files

This repository contains metadata and information on the identity of all included files. However, the actual content of the (sometime large) data files is stored elsewhere. To obtain any dataset component, git-annex is required in addition to Git.

  1. Clone this repository to the desired location.

  2. Enter the directory with the local clone and run:

    git annex init
    

    Older versions of git-annex may require you to run the following command immediately afterwards:

    git annex enableremote mddatasrc
    

Now any desired dataset component can be obtained by using the git annex get command. To obtain the entire dataset content run:

git annex get .

Keep data up-to-date

If updates to this dataset are made in the future, update any local clone by running:

git pull

followed by:

git annex get .

to fetch all new files.
