[QE-users] Error in Boltztrap code, while performing Spin Orbit Coupling (SOC) calculation

[Sadhana Matth SVNIT]

Hi everyone,

We have performed a calculation for material CoHfSi with spin orbit
coupling (SOC), using BoltzTrap code. In the SOC case, we choose the full
relativistic pseudopotential and added two flags, flags are such as
lspinorb = .true.
noncolin = .true.

I am getting an error after this command

*btp2 interpolate -m 2 -e -0.5 ./  *

 The error is
Traceback (most recent call last):
  File "/home/hp/.local/bin/btp2", line 8, in <module>
    sys.exit(btp2_main())

1358, in _parse_ESPRESSO_bands
    raise ValueError(
*ValueError: non-collinear ESPRESSO calculations are not supported yet*
Please help me to solve this error.
I have also done this calculation for without spin orbit coupling, I was
not getting any error.
In the spin-orbit coupling case, scalar relativistic pseudopotential is
taken and those flags are not added (lspinorb = .true. , noncolin = .true.).

These are my input files

Thanks and regards
