DFT+SOC --- bandgnu13 generates only BANDDAT1 file.

Dear Prof. Ozaki and OpenMX experts,

I have calculated WTe2 (including the SOC).
The calculation finishes normally.

when I convert ".Band" file with "bandgnu13" to a gnuplot format, it generates only "BANDDAT1" file.

I am sure that it should generate both "BANDDAT1" and "BANDDAT2" files. (I double-checked the same dat file on another server and it generates both files correctly).

The problem exists for all SOC calculations (I mean other materials too).

I also tried to generate the BANDDATs files with another "bandgnu13" (on another system) for the calculated ".Band" file, but the same problem. (to check if "bandgnu13" works properly on that system or not).

I also re-installed the openmx. the installation finishes normally and other calculations get correct results.

Have you ever seen the same problem?
any suggestion will be appreciated.

Thanks

Best regards,
Maedeh

Dear Maedeh

It is natural.
The Kohn-Sham eigenvalue does not have a spin index for noncolinear (SOI) case.
You can see it from the spinor Kohn-Sham equation.

Dear Mitsuaki Kawamura,

Thank you so much for your reply.

How is it natural?
Do you mean that the correct result should have only 1 "BANDDAT" file?

let me explain a little more:
I have two different installed openmx (different Settings of CC, FC, and LIB) on two different servers. The same dat file gives me 2 "BANDDAT" files on one server and 1 "BANDDAT" file on another.

I want to say if it was related to "spin index", then the output files in both systems should be the same.

or I have misunderstood something here.

Best regards,
Maedeh
