nimare.extract.fetch_neurosynth

fetch_neurosynth(data_dir=None, version='7', overwrite=False, **kwargs)[source]

Download the latest data files from NeuroSynth.

Changed in version 0.0.10:

  • Use new format for Neurosynth and NeuroQuery files.

  • Change “path” parameter to “data_dir”.

New in version 0.0.4.

Parameters:

  • data_dir (pathlib.Path or str, optional) – Path where data should be downloaded. By default, files are downloaded in home directory. A subfolder, named neurosynth, will be created in data_dir, which is where the files will be located.

  • version (str or list, optional) – The version to fetch. The default is “7” (Neurosynth’s latest version).

  • overwrite (bool, optional) – Whether to overwrite existing files or not. Default is False.

  • kwargs (dict, optional) – Keyword arguments to select relevant feature files. Valid kwargs include: source, vocab, type. Each kwarg may be a string or a list of strings. If no kwargs are provided, all feature files for the specified database version will be downloaded.

Returns:

found_databases – List of dictionaries indicating datasets downloaded. Each list entry is a different database, containing a dictionary with three keys: “coordinates”, “metadata”, and “features”. “coordinates” and “metadata” will be filenames. “features” will be a list of dictionaries, each containing “id”, “vocab”, and “features” keys with associated files.

Return type:

list of dict

Notes

This function was adapted from neurosynth.base.dataset.download().
