    • The structure with two hydrogen stripes exhibits the most elongated profile of the tube, and it was used to test the effects of the supercell size on the accuracy of the computed energetics. First, the tube was rotated about its axis so that the two symmetry planes were parallel with the cell size, thus maximizing the overlap with the images in two adjacent supercells. An energy of-0.902 eV was obtained in this orientation. Then, the cell size was extended to 28 Å so that the overlap vanished. In this larger cell, the corresponding energy was-0.899, which verifies that the smaller supercell gives satisfactory accuracy.
