<div>Dear Paolo,</div>
<div> </div>
<div>Thank you !</div>
<div> </div>
<div>I just modified input supplied with QE, since i am a newbie to pseudopotential construction..</div>
<div>Does it mean that norm-conserving pseudolization of p states causes this crash problem ?</div>
<div>Actually , there are 2 waves per channel in the input settings, which is not consistent with</div>
<div>crash information ...</div>
<div> </div>
<div>Regards,</div>
