"""
|
|
Automatically finds n, the number of core electrons. Calls qp_set_mo_class
|
|
setting all MOs as Active, except the n/2 first ones which are set as Core.
|
|
If pseudo-potentials are used, all the MOs are set as Active.
|
|
|
|
|
|
|
|
Usage:
|
|
qp_set_frozen_core [-q|--query] EZFIO_DIR
|
|
|
|
Options:
|
|
-q --query Prints in the standard output the number of frozen MOs
