[Wien] geometry optimization with spin-orbit interaction

[Zhiyong Zhang]

Dear All, 

I have a few questions about geometry optimization. Is it possible to do geometry optimization with spin-orbit interaction? If so how do I set it up? I tried the following: 

min_lapw -p -I -sp -i 160 -ec 0.0001 -cc 0.0001 -in1ef

But it didn't work. I would like to do a geometry optimization with the following scf options: 

runsp_lapw -p -i 160 -ec 0.0001 -cc 0.0001 -in1ef -so -I

I can only make the optimization working with the following options though

min_lapw -p -I -sp -i 160

It seems like that I can't (1) specify the s.o. option for geometry optimizations and (2) set the convergence criteria for energy and charge other than the default for geometry optimization. 

Thanks a lot for any help!
