hi
i am doing a calculation which includes spin-orbit coupling. I included the tag LSORBIT in the INCAR file. when i run the job i get following error message
####################################
Full k-point grid generated
Inversion symmetry is not applied
#####################################
what this means
if somebody know then please help

I am also having same problem. Please administrator give the direction how to calculate the relativistic calculation. I read all the posted comments and manual but did not get it.
my POSCAR is
Pt3Ni
