[Pw_forum] error with spin polarized calculation with SOC

[Thaneshwor Kaloni]

Dear QE Users,

I would like to perform spin polarized calculations with SOC.
I am receiving following errors. Could anyone please assist me?

     Parallel version (MPI), running on    10 processors
     R & G space division:  proc/pool =   10

     Current dimensions of program PWSCF are:
     Max number of different atomic species (ntypx) = 10
     Max number of k-points (npk) =  40000
     Max angular momentum in pseudopotentials (lmaxx) =  3
     Waiting for input...
     Presently no symmetry can be used with electric field
