Dear all, The directory structure of PH has changed. Now directory PH has been renamed with PHonon. Inside PHonon you will find the following subdirectories:<br><br>-Doc <br>-examples<br>-Gamma : phonon for gamma only applications<br>
-D3 : third order derivatives<br>-PH : the original phonon code<br><br>The user_guide is in an embrionary stage, any contribution is wellcome. If you find Makefile problems when compiling on some Operating system, we will be very grateful if you send a report to q-e-developers mailing list.<br>
<br>best regards<br><br>Layla<br>
