My computation was stuck because of an error, and even though I was going to turn on these switches( epwwrite = .true. epwread = .false. ep_coupling = .true. elph = .true. epbwrite = .true. epbread = .false. epwwrite = .true. epwread = .false.), there was no way to do the computation and generate the XX.ephmat directory
