nimare.generate.create_neurovault_dataset

create_neurovault_dataset(collection_ids=(8836, 8838, 8893, 8895, 8892, 8891, 8962, 8894, 8956, 8854, 9000), contrasts={'animal': 'as-Animal'}, img_dir=None, map_type_conversion=None, **dset_kwargs)[source]

Download images from NeuroVault and use them to create a dataset.

New in version 0.0.8.

This function will also attempt to generate Z images for any contrasts for which this is possible.

Parameters
  • collection_ids (list of int or dict, optional) – A list of collections on neurovault specified by their id. The collection ids can accessed through the neurovault API (i.e., https://neurovault.org/api/collections) or their main website (i.e., https://neurovault.org/collections). For example, in this URL https://neurovault.org/collections/8836/, 8836 is the collection id. collection_ids can also be a dictionary whose keys are the informative study name and the values are collection ids to give the collections human readable names in the dataset.

  • contrasts (dict, optional) – Dictionary whose keys represent the name of the contrast in the dataset and whose values represent a regular expression that would match the names represented in NeuroVault. For example, under the Name column in this URL https://neurovault.org/collections/8836/, a valid contrast could be “as-Animal”, which will be called “animal” in the created dataset if the contrasts argument is {'animal': "as-Animal"}.

  • img_dir (str or None, optional) – Base path to save all the downloaded images, by default the images will be saved to a temporary directory with the prefix “neurovault”

  • map_type_conversion (dict or None, optional) – Dictionary whose keys are what you expect the map_type name to be in neurovault and the values are the name of the respective statistic map in a nimare dataset. Default = None.

  • **dset_kwargs (keyword arguments passed to Dataset) – Keyword arguments to pass in when creating the Dataset object. see nimare.dataset.Dataset for details.

Returns

nimare.dataset.Dataset – Dataset object containing experiment information from neurovault.
