# 1. Build MO Theory model

fname = 'dichloropyridine26_q+0'
mo = MOTBasedTool.from_file(fname + '.fchk')

# 2. Generate cube file(s) and script(s) for visualizing HOMO/LUMO
#    Files generated are dichloropyridine26_q+0_mo{index}.cube/.vmd
#    To visualize the iso-surface, use command: $ vmd -e dichloropyridine26_q+0_mo{index}.vmd

cub = UniformGrid.from_file(fname + '.fchk', spacing=0.2, extension=5.0)
mo.generate_scripts(fname, spin='a', index=mo.homo_index[0], isosurf=0.025, grid=cub)
mo.generate_scripts(fname, spin='a', index=mo.lumo_index[0], isosurf=0.025, grid=cub)

Total running time of the script: ( 0 minutes 12.226 seconds)
