"""
|
||
|
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.
|
||
|
|
||
|
For elements on the right of the periodic table, qp_set_frozen_core will work
|
||
|
as expected. But for elements on the left, a small core will be chosen. For
|
||
|
example, a Carbon atom will have 2 core electrons, but a Lithium atom will have
|
||
|
zero.
|
||
|
|
||
|
|
||
|
Usage:
|
||
|
qp_set_frozen_core [-q|--query] EZFIO_DIR
|
||
|
|
||
|
Options:
|
||
|
-q --query Prints in the standard output the number of frozen MOs
