I updated Multiwfn today, now this function can use the file only containing atomic coordinate such as .xyz as input file.
Will a function for outputting a .wfn file with promolecular wavefunction be added someday so that only xyz and "atomwfn" can be used to generate this file, and not a .wfn file with real wavefunction, calculated in the same basis as the atoms in "atomwfn"?
