This is my lines of code:
structure=Structure.from_file(‘Ti2C.cif’)
asf=AdsorbateSiteFinder(structure)
ads_sites=asf.find_adsorption_sites()
adsorbate = Molecule([“Na”,“H”,‘H’], [[0, 0, 0], [0, 0, 4.00],[0, 0, 4.74]])
ads_structs=asf.generate_adsorption_structures(adsorbate,repeat=[1,1,1],find_args={“distance”:1.60})
