[Pw_forum] R: Problems computing cholesky

[Carlo Motta]

Dear Lorenzo and Paolo,

thank you for getting me back on this.
Actually, replacing the pseudopotential of V with V.pbe-sp-van.UPF (from the database) solves the problem. So, I am using norm-conserving pseudopotentials for O and Cs and ultrasoft pseudopotential for V. I read that mixing should not be a problem.

One thing is still concerning me: all the pseudopotentials are scalar-relativistic (as read from the database). 
V.pbe-sp-van.UPF
O.pbe-mt.UPF
Cs.pbe-mt_bw.UPF
However, in the scf output I get:
"At least one non s.o. pseudo"

Is that expected?

Also, with the same set of pseudopotentials I did a s.o. (lspinorb and noncolin = true) and a non-s.o. calculations, and the bandstructure is identical.

Many thanks again,
