<DIV>Dear Prof. Baroni,</DIV>
<DIV> The problem about display, I have solved, thank you very much. Recently, I encounter some problems, pwscf only do periodic hybrid density functional theory calculation, it could do any other general density functional theory calculation? Is there any principle about settings of k-point and cut-off energy? </DIV>

<DIV>Thanks in advance</DIV>
<DIV>Best wishes</DIV>
