Hello!

I need to preprocess this data using fmriprep. And for that i need dataset description json files, which i struggle to create. Maybe you can give me a hint how to get them or you already have them?

Thank you,
Tania

Hi @nomoreofanime,

You can look at example datasets here: GitHub - bids-standard/bids-examples: A set of BIDS compatible datasets with empty raw data files that can be used for writing lightweight software tests.

For example, here is one of the dataset_description.json files:

{
    "Name": "Multisubject, multimodal face processing",
    "License": "CC0",
    "Authors": [
        "Wakeman, DG",
        "Henson, RN"
    ],
    "Acknowledgements": "This work was supported by the UK Medical Research Council (SUAG/010\nRG91365) and Elekta Ltd. We would also like to acknowledge the contribution of Andre van der Kouwe and the A.A. Martinos Center for Biomedical Imaging (MGH) for providing the Multi-Echo FLASH sequences used in this work.",
    "HowToAcknowledge": "Cite this paper: https://www.ncbi.nlm.nih.gov/pubmed/25977808 and consider including the following message: 'This data was obtained from the OpenNeuro database. Its accession number is ds000117'",
    "Funding": [

    ],

        "https://openfmri.org/dataset/ds000117/",
        "ftp://ftp.mrc-cbu.cam.ac.uk/personal/rik.henson/wakemandg_hensonrn/Publications/"
    ],
    "BIDSVersion": "1.8.0",
    "DatasetDOI": "10.18112/openneuro.ds000117.v1.0.4"
}

Best,

the bids starter kit also has templates for a lot of typical bids files:

and the relevant section of the specification has an example as well:
