I don't see an obvious problem with this input file (although a 12 A
cutoff is awfully small for an aperiodic system).

What happens if you put a space before &cntrl? Does that fix it? What
about putting a space before the /? If neither of those works, try
replacing / with &end

Do any of those work?
