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
