Hi,
if you wanna dig out some useful information related to your question ,
you can try to search with google , refined  keywords with 'pwscf' or
others.

Please read the instructions such as   INPUT files in $espresso/Doc, or
tutorials mentioned in Axel and nicola's last mails.


hope help.

regards,

hai-ping
