add_labels(labels, directory=None, check_consistency=True)

Add the given list of strings as labels for the terms.

Parameters

labelslist of str or str

Labels for each term to add to the object. If list, is assumed to be labels. If str, is assumed to be a file name to load from.

directorySCDB or str, optional

Folder or database object specifying the file location, if loading from file.

check_consistencybool, optional, default: True

Whether to check the object for consistency after adding labels.

add_terms(terms, term_type=None, directory=None, append=False, check_consistency=True)

Add terms to the object.

Parameters

termslist or dict or str

Terms to add to the object. If list, assumed to be terms, which can be a list of str or a list of list of str. If dict, each key should reflect a term_type, and values the corresponding terms. If str, assumed to be a file name to load from.

term_type{‘terms’, ‘inclusions’, ‘exclusions’}

Which type of terms to are being added.

directorySCDB or str, optional

Folder or database object specifying the file location, if loading from file.

appendboolean, optional, default: False

Whether to append the new term(s) to any existing terms. If False, any prior terms are cleared prior to adding current term(s).

check_consistencybool, optional, default: True

Whether to check the object for consistency after adding terms.

Examples

Add search terms, from a list:

>>> base = Base()
>>> base.add_terms(['frontal lobe', 'temporal lobe', 'parietal lobe', 'occipital lobe'])

Add inclusion terms, from a list:

>>> base.add_terms([[], ['brain'], [], []], term_type='inclusions')

Add exclusion terms, from a list:

>>> base.add_terms([['prefrontal'], [], [], []], term_type='exclusions')

check_terms(term_type='terms')

Print out the current list of terms.

Examples

Check added terms:

>>> base = Base()
>>> base.add_terms(['frontal lobe', 'temporal lobe', 'parietal lobe', 'occipital lobe'])
>>> base.check_terms() 
List of terms used:

frontal lobe    : frontal lobe
temporal lobe   : temporal lobe
parietal lobe   : parietal lobe
occipital lobe  : occipital lobe

Attributes

term_type{‘terms’, ‘inclusions’, ‘exclusions’}

Parameters

labelstr

The label of the search term.

Returns

indint

Raises

IndexError

If the requested term label is not found.

get_term(label)

Get a search term from the object.

Parameters

Returns

termTerm

The full search term definition.

property has_terms

Indicator for if the object has terms.

property labels

The labels for each term.

make_search_term(label)

Create the combined search term for a selected term.

Parameters

labelstr or int

The requested term. If str, is the label of the term. If int, is used as the index of the term.

property n_terms

How many terms are included in the object.

unload_labels(verbose=True)

Unload labels from the object.

unload_terms(term_type='terms', reset=True, verbose=True)

Completely unload terms from the object.

Examples

Unload added terms:

>>> base = Base()
>>> base.add_terms(['frontal lobe', 'temporal lobe', 'parietal lobe', 'occipital lobe'])
>>> base.unload_terms()
Unloading terms.

Attributes
