Dear Matteo,
Thank you for this elaborate reply. This weekend I figured out the most
severe problems, I had.
Yes, this segfault was produced by not including gipaw information. Dump
error of mine.
Concerning my upload, I apologize that both directories are not exactly
consistent but anyway, the only dat-file contained in
diamondh_uspp_5.2.0.tar.gz is the xanes.dat (see attachement for
comparison).
But as this issue is resolved with an appropriate version and because
the calculations contain some lousy mistake (see below) it is not
relevant anymore.
I already know the tutorial by heart, but this did not save me from
another error:
The full wave function is contained in the <prefix>.wfc (ld1.wfc) file
while only the radial part of the 1s state is needed. As fledgling I did
not get this aspect. So I always replaced the wfc-file from the tutorial
with the wfc from ld1-output. In the tutorial this error is catched by
using the (legacy) upf2plotcore.sh script. I found this error only by
comparison of the script's output with the wfc file. I also needed a
compatible UPF-file I could not produce myself with a recent version of
the atomic package. So it if known it is easy to create the necessary
wfc-file manually.
For me it is also not trivial to apply the information in the hands-on
to USPPs. So I think although it is a neat and detailed tutorial, it is
not up to date.
PAW are not compatible??? With a now hopefully fine setup I produced
some quiet promising XAS spectra of MgO. I cannot say it for sure but in
this tests some relevant peaks are repoduced using a 2x2x2 and a 3x3x3
supercells. I cannot ensure that they are not faulty, but the features
are visible.
Here is my setup with the work directories scrubbed:
http://www.file-upload.net/download-10876487/messing_with_PAW.tar.gz.html
Experimental reference: 2013 J. Phys.: Conf. Ser. 417 012065
So although the PAW results are wrong. Did I correctly generate the
pseudopotential concerning a reference state?
During generation I also did not ionize the reference state because I
did not want to touch more parameters than needed. The results still
looked acceptable. Does this necessarily lead to spurious errors?
How do I correctly include a reference state to a pseudopotential from
the PSlibrary?
Thanks again for your kind reply.
