[CP2K-user] [CP2K:17240] Re: Band Structure Sets with cp2k_bs2csv.py

[Krack Matthias (PSI)]

You can use pip to install the cp2k-output-tools like the cp2k-input-tools<https://github.com/cp2k/cp2k-input-tools#installation>: pip install cp2k-output-tools
Alternatively, you can run in the folder cp2k-output-tools “pip install .”
After a successful installation (note the requirements) the command “cp2k_bs2csv” should be available.

Thank you for the reply but I'm quite confused about which script you are talking of. I went to this page
https://github.com/cp2k/cp2k-output-tools/tree/develop/cp2k_output_tools
and I'm quite confused about which python script to use. Should I use cli.py or bandstructure_parser.py? Could you please guide me through this

Hi Anjali

You refer to a forked cp2k-output-tools repository which is not up-to-date. Try the original master https://github.com/cp2k/cp2k-output-tools instead of that fork.

Dear all,

as far as I can see, the format of the output file is changed in the developing version (or maybe earlier).
The  https://github.com/ltalirz/cp2k-output-tools/blob/develop/cp2k_output_tools/scripts/bandstructure.py  script does not work for me now.
Can anyone suggest me something please? (.bs attached)

Best wishes,
Anjali

If you write "cp2k_bs2csv" do you see:

Hi Dmitry
Thank you so much for your reply!
But the problem is that script from the link you provided doesn't work for me and i don't understand why.
it just does nothing. I thought you did some corrections in the code.

Hi Alexander,

first of all install
https://github.com/cp2k/cp2k-output-tools

it will transfer .bs file to .csv file ready for figure.
If you get .csv, I can try my second script to make a figure.
But you need to edit this script by hand, I hope to make better script later.
Ask me for details.

Hello, Dmitry

Could you please provide the working script? or give an idea how you found a solution for the problem.
thank you in advance.

Best regards, Alexander

So. Finally, it really works.
But I was not able to find it quickly without your help. And the script in exercises is outdated.
I think it is a good idea to make tools like it more visible at cp2k.org<http://cp2k.org>.

Hi Dima,

I've updated the script there to work with CP2K as on May 5th and there
were no changes to the relevant output since then as far as I see?

Can you please test whether it works and if not make a bugreport on
https://github.com/cp2k/cp2k-output-tools/issues ?

Best,
Tiziano
