UT theoretical chemistry code forum

If I want to calculate the NEB between 2 structures of different unit cell size, for eg, the HEX version of MoTe2 has 1 Mo and 2 Te in its unitcell,whereas the T-dash version has 2 Mo and 4 Te in its unit cell, how do I match the 2 structures appropriately? I am creating a supercell of POSCAR1 in x direction as 2X1 to match the lattices of both the strcutures, but I believe, I am making a mistake in this process, which is messing up the NEB. As ordering is important in NEB, can you please advise how to accurately process this?


Thanks
