<p>Hi,</p><p><br></p><p>I have problem generating atomic-like wave
functions from ultrasoft pseudopotential (USPP) <br></p><p>using the
upf2plotcore.sh script in QE-5.1 XSpectra package. I went over all of
the examples <br></p><p>of diamond, SiO2 and NiO xspectra calculations. Now I want
try it in Fe2O3 hematite system <br></p><p>using DFT-GGA+U method. The USPP I chose
to use for Fe is called "Fe.pbe-nd-rrkjus.UPF". <br>I down load it from QE
website.</p><p><br></p><p>However, when I use the same command shown in the example script to generate atomic-like <br>wave functions to get Fe.wfc:</p><p>....../espresso-5.1/XSpectra/tools/upf2plotcore.sh ~/my_pseudo_dir/Fe.pbe-nd-rrkjus.UPF > ./Fe.wfc</p><p><br></p><p>I got an empty Fe.wfc file, which only has one line:</p><p># number of core states 0 =</p><p><br></p><p>I
didn't get this problem when I was working on those examples of
diamond, SiO2 and NiO <br>using provided pseudopotentials in the package
like:</p><p>C_PBE_TM_2pj.UPF</p><p>Si_PBE_USPP.UPF</p><p>Ni_PBE_TM_2pj.UPF</p><p>They
are in ....../espresso-5.1/XSpectra/examples/pseudo. They could
generate proper C.wfc, <br>Si.wfc and Ni.wfc for following xspectra
calculations.</p><p><br></p><p>So I'm wondering if there is any specific
"requirement" for the choose of USPP in xspectra <br></p><p>calculations. There
are many different Fe-USPP in QE website. Do you know which of them can
<br>be used to generate Fe.wfc?</p><p><br></p><p>Thank you,</p><p>Xu Huang <br></p><br>
