This means that you cannot use -mat_type fftw. Probably because no combination
of options can currently initialize it correctly. It is fine to leave
out USFFT until this
is possible.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
