Calls qp_set_mo_class setting all MOs as \fBActive\fP, except the n/2 first ones which are set as \fBCore\fP\&. If pseudo\-potentials are used, all the MOs are set as \fBActive\fP\&. .sp For elements on the right of the periodic table, \fIqp_set_frozen_core\fP 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. .SH USAGE .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C qp_set_frozen_core [\-q] EZFIO_DIR .ft P .fi .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-q Prints in the standard output the number of core electrons. .UNINDENT .SH AUTHOR A.
