pwtools/lambda.f90 should calculate it. Unfortunately it has
never been updated to read the new file formats produced
by the electron-phonon calculation, so it will require some
Paolo Giannozzi, Democritos and University of Udine, Italy

         it has never been updated to read the new file formats? is it mean we
must modify
inputfile(which lambda.f90 read from)? or modify anyother? I don't understand what
you mean. please give more details.thank you.
