Dear Pwscf users and developers,

               In Quantum espresso i can get the same type Norm-Conserving
pseodopotentials for all the elements like case.pbe-mt_fhi.UPF. But in the
case of ultra soft pseudo potentials it is different. For example if my
system consist of Nb and Sn elements, i can get
Nb element and
Sn element. Different methods are used in developing these potentials.

             Now my question is, can i use these potentials in my
calculations?. If i use one NC and one ultrasoft what will happen?.

Thank you in advance...
