[Pw_forum] Regarding PDOS

Dear All,

I am a new user in QE package v 5.3.0. Now I am posting a query regarding
the calculation of pdos for a system consisting of 16 atoms. I have
followed the steps which i mention below

$ pw.x <rootname.scf.in> rootname.scf.out
$ pw.x <rootname.nscf.in> rootname.nscf.out
$ projwfc.x <rootname.pdos.in> rootname.pdos.out

I got lots of files of projections. I have confused how to plot all. Let I
have put 16 atoms of four types like C, O, N and H. So, I have got more
files of oxygen atom with projections of individual orbitals. If I got
more O atoms files, which one I will consider. I have given the position
file which will clear the query.

This gave me files like 'rootname.pdos_atm#1(C)_wfc#1(s)',
'rootname.pdos_atm#1(C)_wfc#2(p)', 'rootname.pdos_atm#10(C)_wfc#1(s)' and
'rootname.pdos_atm#1(C)_wfc#2(p)'

Thus, I got more files for carbon, like others also. When, I plot, both
positions show different plots. I do not get how to get the pdos of
individual atoms of my system. KIndly suggest me some tricks to solve my
query.

Thanking in advance.
