This work is a combination of experiment and theoritical investigation on MR of ZrSiS. We only provide our simulation data here. The input-vasp folder includes all input files (INCAR, KPOINTS, POSCAR and POTCAR) for DFT calculation by using vasp. And the wannier90.win file is for generating the TB Hamiltionian. Change the tage in input.dat, one can calculate Fermi surface (fig4 c, tag: BulkFS_calc) or magnetoresistance (tag: Boltz_OHE_calc). Also one needs to specify the orientation of magnetic field B.(simulation data in fig4 a b d e f).
