Unrestricted calculations with PBC in QMCPAC

Hi everybody
I'm new at QMCPACK.
I want to use qmcpack to do QMC calculation on transition metal oxid like NiO by using pyscf to generate input file.

I run the pyscf input file for 1st step. (KUHF calculation method)
Now I got an error :
**Unrestricted calculations with PBC not supported (yet) - contact Developers**

I have a 2 questions:

1) How can we define an AFM phase for such materials in qmcpack?
Is it implemented in qmcpack or not?

2) I want to use pseudopotental in HF calculation by PySCF, now my question is :
Do they use the same PseudoPotential ?
