Dear All,
Does bandup compatible with QE-6.3 xml data file. I am getting similar error in both QE-6.3 & 6.5 (I renamed data-file-schema.xml --> data-file.xml),

ERROR (read_qe_evc_file): Problems opening the XML data-file "/home/soumyadeep/Downloads/bandup-master/tutorial/Quantum_ESPRESSO/example_2_bulk_Si/test_soumya/BS_SC/Si.save/data-file.xml"!

with many thanks and best regards
Soumyadeep

Dear all,

Thank you very much for your suggestions.

@Pietro: Do I understand you correctly that there is already some work
in progress on making bandUP compatible with the newest QE version?
Please let me know if there is any way I can help, e.g. with testing
the code.

Best regards,

Dominik

Dear all

I am preparing the PR for the bandUP repository. As soon as ready  I
will let you know.

Dear Dominik,

I firmly believe that you should opt for implementing the new XML
scheme inside BundUP or, if lacking time, use OLD_XML with QE 6.3 as
already suggested.

in case you are interested in following this path, here
https://github.com/yambo-code/yambo/tree/master/interfaces/p2y

you can find a small library (qexsd_p2y.F) to read the new XML fmt
of QE, which parallels the one used for the old format (qexml.F).
Passing from one to the other should be quite straighforward.

That being said, stimulated by your question, I went back to the
code I wrote a few years ago as an exercise:
https://bitbucket.org/bonfus/unfold-x .

@Pietro: thanks for pointing out

Andrea

It happens to be working with QE v6.5, it just needed a couple of
minor changes that I just pushed to the repository.

If, for no good reason, you happen to give it a try, just let me
know.

Best regards,
Pietro

Hi Dominik,

I did give it ago about 1.5 years ago with QE6.3 if I remember
correctly compiled with the OLD_XML flag (it was dropped in later
releases), so I believe that unless you need some very new features
you probably can use slightly older version.

Best regards,

Dear QE community,

I am looking for recommendations as to which code to use for
unfolding a supercell band structure.

I did find the BandUP code
(https://github.com/band-unfolding/bandup), but it seems the code
does not support the new XML format of Quantum Espresso.

Does anyone know of an unfolding code that works with the latest QE
version? If not, I would also be glad to hear your experience with
the BandUP code, to know if it might be worth it to implement this
support myself.

Thank you and best regards,
Dominik Gresch
