Methods

add_atlas_set(name, atlas_labels, spatial_image)

Creates an atlas set: 1- for each region specified by a label and name in atlas_labels, creates associated ExplicitVBR and symbols Tuple[region_name: str, Region] 2- groups regions in an AbstractSet[Tuple[str, Region]] symbol with specified name

add_constraint(antecedent, consequent)

Creates an right implication of the consequent by the antecedent and adds the rule to the current program: antecedent -> consequent

add_region(region[, name])

Adds region fe.Symbol to symbol_table

add_region_set(region_set[, name])

Creates an AbstractSet fe.Symbol containing the elements specified in the iterable with a List[Tuple[Region]] format

add_symbol(value[, name, type_])

Creates a symbol with given value and adds it to the current symbol_table.

add_tuple_set(iterable[, type_, name])

Creates an AbstractSet fe.Symbol containing the elements specified in the iterable with a List[Tuple[Any, ...]] format (see examples).

all(quantified_variable, body)

Universal predicate on the body.

create_region(spatial_image[, label, ...])

Creates an ExplicitVBR out of the voxels of a dense spatial_image with specified label

del_symbol(name)

Deletes the symbol with parameter name from the symbol_table

execute_datalog_program(code)

Execute a Datalog program in classical syntax.

exists(quantified_variable, body)

Existential predicate on the body.

get_symbol(symbol_name)

Retrieves symbol via its name, either providing a fe.Expression with the correct name or the name itself

load_neurosynth_mni_peaks_reported(data_dir)

Load the coordinates for the peaks reported by studies in the Neurosynth dataset.

load_neurosynth_study_ids(data_dir[, name, ...])

Load all study ids (PMIDs) that are part of the Neurosynth database.

load_neurosynth_term_study_associations(data_dir)

Load TF-IDF values for each (term, study) association within the Neurosynth database.

make_implicit_regions_explicit(affine, dim)

Raises NotImplementedError for now

new_region_symbol([name])

Returns symbol with type Region

new_symbol([type_, name])

Creates a symbol and associated expression, optionally specifying it's type and/or name

predicate_parameter_names(predicate_name)

Get the names of the parameters for the given predicate

query(*args)

Performs an inferential query on the database.

reset_program()

Clears current symbol table

solve_all()

Returns a dictionary of "predicate_name": "Content" for all elements in the solution of the Datalog program.

sphere(center, radius[, name])

Creates a Region symbol associated with the spherical volume described by its center and volume

magic_sets_rewrite_program

__init__(program_ir=None)

Query builder with query, Region, Neurosynth capabilities

Parameters:
