How to use the miscnn.data_loading.interfaces.NIFTI_interface function in miscnn

def test_IOI_NIFTI_predictionhandling(self):
        interface = NIFTI_interface(pattern="nifti")
        sample_list = interface.initialize(self.tmp_data.name)

        pred = interface.load_prediction("pred.nifti", self.tmp_data.name)
        self.assertTrue(np.array_equal(pred, self.seg))

        self.assertEqual(len(sample_list), 1)
        self.assertEqual(sample_list[0], "nifti")
