I assume that you have correctly changed the number of electrons in both
case.in2(c) and case.inm.

Beyond that, please execute and send me the output (or the list)

tail -n 50000 *.scf | grep -e :ADIST -e :DIR -e :MV -e GREED -e :FRMS -e
:ENE -e :CHARG -e PRATT \
-e :DIS -e "MIXING SC" -e ":RANK" -e PLANE | \
grep -v -e "with 1.0" -e scheme -e CONTRIBUTION | \
tail -44

Without some more information about what is going on it is impossible to
say anything beyond vague and probably incorrect general statements.
