[Pw_forum] Error while trying to calculate phonons on a grid

[Gabriele Sclauzero]

Are you using the same version of pw.x and ph.x? In the latest version, the code writes and reads the parameter U_PROJECTION_TYPE to the data-file, but previous versions. If you use pw and ph from the same distribution, I think you should not find this problem anyway. Let me know if this is not the case.
