[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 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())
  File

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 without spin orbit coupling, I was not
getting any error.
Without spin orbit coupling case, scalar relativistic pseudopotential is
taken and those flags are not added (lspinorb = .true.
noncolin = .true.)

Thanks and regards
Sadhana
