<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Dear Wei Zhou,<br><br> you are strongly encouraged to move to the latest version of PWscf (which you can<br>
download from <a href="http://www.quantum-espresso.org/" target="_blank">www.quantum-espresso.org</a> or <a href="http://qe-forge.org/" target="_blank">qe-forge.org</a>), unless you have a specific reason<br>(other than "I don't want to make any little effort in learning how to use the new input<br>
syntax") to use a very old version such that you mention (about 8 yrs old!).<br> The older versions are no more maintained and lack of many interesting features and<br>improvements that have been added with time and that you may need sooner or later.<br>
Moreover, I think you will not get much assistance from the developers or from the<br>forum users if you insist in using that version.<br> You will not even be able to understand the large number of examples which are included<br>
in the latest versions if you don't know the current input syntax of the code (which has<br>more or less stabilized in the last years).<br><br>Hope I've convinced you,<br><br><br>Cheers<br><br>GS<br>
