Error in opening file ./XX.ephmat/freq

[wqy1]

Dear community,
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

Hi wqy1,

Please set 'ephwrite = .true.' in your input so that the XX.ephmat directory will be created and required data will be written to files to solve the Eluiashberg equations.

Happy EPWing,
Hari
