        z=$(echo $i | grep TT)
        if [ x"$z" = x ]
        then
                z=$(echo $i | sed -e 's/TB/T/g')
                while [ 1 ]
                do
                        z=$(echo $z | sed -e 's/TT/T/g')
                        if [ x"$(echo $z | grep TT)" = x ]
                        then
                                break
                        fi
                done
