[Pw_forum] phonon dispersion for graphene

[Stefano Baroni]

Dear Elie,

may I respectfully ask how much time do you allow yourself to think how to solve a problem between the time you encounter it and the time you hit "return" on a request to this mailing list? May I suggest that a reasonable time could be something in between a few hours and a day? (well a few days may well be worth of it for an important problem, up to several weeks or months, when this requires attending a course).

Regards,
SB

The error probably means that something was wrong while reading the previous file...I ran a scf calculation (pw.x) followed by the ph.x. I would appreciate it if you can suggest how to fic this problem..I repeated the calculations several times  but in vain..
