nilearn.datasets.select_from_index#
- nilearn.datasets.select_from_index(urls, inclusion_filters=None, exclusion_filters=None, n_subjects=None)[source]#
Select subset of urls with given filters.
- Parameters
- urlslist of str
List of dataset urls obtained from index download.
- inclusion_filterslist of str, optional
List of unix shell-style wildcard strings that will be used to filter the url list. If a filter matches the url it is retained for download. Multiple filters work on top of each other. Like an “and” logical operator, creating a more restrictive query. Inclusion and exclusion filters apply together. For example the filter ‘task-rest’’ would keep only urls that contain the ‘task-rest’ string.
- exclusion_filterslist of str, optional
List of unix shell-style wildcard strings that will be used to filter the url list. If a filter matches the url it is discarded for download. Multiple filters work on top of each other. Like an “and” logical operator, creating a more restrictive query. Inclusion and exclusion filters apply together. For example the filter ‘task-rest’ would discard all urls that contain the ‘task-rest’ string.
- n_subjectsint, optional
Number of subjects to download from the dataset. All by default.
- Returns
- urlslist of string
Sorted list of filtered dataset directories.
