actually there is also another reason. The current implementation of electron-phonon coefficients is not satisfactory. There are better algorithms around, thus investing in the old algorithm doesn't seem such a great idea. Software implementing Wannier interpolation for electron-phonon calculations has been released recently and works in conjunction with QE: see epw.org.uk P. --- Paolo Giannozzi, Dept of Physics, University of Udine via delle Scienze 208, 33100 Udine, Italy Phone +39-0432-558216, fax +39-0432-558222
