- GasByName.labels(pores=, throats=, element=None, mode='union')¶

mode (str, optional) –

’or’, ‘union’, ‘any’: (default) Returns the labels that are assigned to any of the given locations.

throatsare given, the results are filtered according to the
Technically, ‘nand’ and ‘xnor’ should also return pores with none of the labels but these are not included. This makes the returned list more useful.
