1. Generally, is it fine to apply one psuedo potential for geo relaxation and scf calculation, while applying another pseudo potential for electronic property calculation such as dos and band?  Any reference/criteria to choose pseudo potentials, for example vanderbilt versus atomic ? </div>

2. Is it faster and good enough to start geometry optimization with non-spin polarized calculation and then switch to spin-polarized calculation with initial geometry optimized in non-spin polarized structure? </div><div style="color:rgb(34,34,34);font-size:13px;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;font-family:arial,sans-serif">
