As a follow up to my last note. Specifically you should modify the
generate_pqr() section of mm_pbsa_calceneent.pm. This is the
modification I added to my code . . .

                 "Na+" => 1.200 + 1.400,
                 "Cl-" => 1.700 + 1.400,
                 "MG" => 1.180 + 1.400,
                 "F" => 1.470 + 1.400,
                );

Have fun with this...
