<p>Hi all,</p>
<p><br>
</p>
<p>I am a beginner at QE and want to generate a pseudopotential with ld1.x but have difficulties understanding the config keyword. </p>
<p>Why does gipaw occupation for C obtained at the QE homepage (C.pbe-mt_gipaw.UPF) have config=2s2 2p1.5 but for others such as kjpaw etc have config=<span style="font-family:Calibri,Helvetica,sans-serif,Helvetica,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px">2s2
2p2?</span></p>

<p><span style="font-family:Calibri,Helvetica,sans-serif,Helvetica,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px">Also, what config is recommended for generating a gipaw PP
for N? </span></p>
