discretization

hi all,
        i am working on diabetes dataset of women.it have attributes like 'bio mass index','plasma glucose','triceps sft','age','pregnant'......and few other.in this i have to predict whether a patient will develop diabetes or not.now in this i used user based discretization to discretize few attribute........few other attributes i have to discretize with bin discretization....................now my problem is that........"after discretizing few attribute with user based discretization how to discretize remaning other with bin discretization??"......
                  with regards
