[求助] 请教几个tripos原子类型的问题

本人刚学SYBYL ,对tripos原子类型不是很熟悉,请问图片1中左上方苯环上CH2NH2处的N是N.3还是N.pl3,因为我用Sketch模块搭建分子时,sybyl最初自动判断是N.pl3;吡啶环旁边的NH2的N应该是N.pl3吧;右边哌啶环上的N与乙酰基相连时是N.3还是N.am,因为我搭建分子时,sybyl最初自动判断是N.am;
图片2中左上方苯环上的NHCOMe处的N应该是N.pl3还是N.am,因为我用Sketch模块搭建分子时,sybyl最初自动判断是N.pl3。
本人觉得网上搜到的Tripos公司给的原子类型说明太粗略,没有结合太多复杂的实际例子来讲解;而有一个例子是我搜到的,却很粗略,希望大家提供更好的例子资源来讲解。请教几个tripos原子类型的问题

我从网上摘了一段,不知道对不对
1.6         If element_symbol is C then

1.6.1                 If num_bond .ge. 4 .AND. all bonds are single then
                atom_type is C.3

1.6.2                 If num_bond .eq. 3 .AND. all bonds are acyclic .AND.
                all bonds are to nitrogen .AND. each nitrogen forms bonds to 2
                other atoms both of which are not oxygen then atom_type
                is C.cat

1.6.3                 If num_bond .ge. 2 .AND. 2 bonds are aromatic then atom_type
                is C.ar

1.6.4                 If ( num_bond .eq. 1 .OR. num_bond .eq. 2 ) .AND. one bond is
                triple then atom_type is C.1

1.6.5                 If element_symbol is C and none of the above then atom_type
                is C.2

1.7         If element_symbol is O then

1.7.1                 If num_nonmet .eq. 1 then

1.7.1.1                 If bond is to carbon .AND. carbon forms a total of 3
                        bonds, 2 of which are to an oxygen forming only 1
                        non-metal bond then atom_type is O.co2

1.7.1.2                 If bond is to phosphorus .AND. phosphorus forms at
                        least 2 bonds to an oxygen forming only 1 non-metal
                        bond then atom_type is O.co2

1.7.2                 If num_bond .ge. 2 .AND. all bonds are single then atom_type
                is O.3

1.7.3                 If element_symbol is O and none of the above then atom_type
                is O.2

1.8         If element_symbol is N then

1.8.1                 If num_nonmet .eq. 4 .AND. all bonds are single then atom_type
                is N.4

1.8.2                 If num_bond .ge. 2 .AND. 2 bonds are aromatic then atom_type
                is N.ar

1.8.3                 If num_nonmet .eq. 1 .AND. bond is triple then atom_type is N.1

1.8.4                 If num_nonmet .eq. 2 .AND. ( bonds are double, double .OR.
                bonds are single, triple ) then atom_type is N.1

1.8.5                 If num_nonmet .eq. 3 .AND. one bond is to C=O or C=S then
                atom_type is N.am

1.8.6                 If num_nonmet .eq. 3 then

1.8.6.1                 If one bond is not single then atom_type is N.pl3

1.8.6.2                 If all bonds are single then

1.8.6.2.1                         If one single bond is to an atom that forms a
                                bond of type double, triple, aromatic or
                                delocalised .AND. one other single bond is to H
                                then atom_type is N.pl3

1.8.6.2.2                         If one single bond is to an atom that forms a
                                bond of type double, triple, aromatic or
                                delocalised .AND. neither of the other single
                                bonds are to H .AND. sum_of_angles around
                                N .ge. 350 deg then atom_type is N.pl3

1.8.6.3                 If num_nonmet .eq. 3 otherwise then atom_type is N.3

1.8.7                 If element_symbol is N and none of the above then atom_type
                is N.2

1.9         If element_symbol is S then

1.9.1                 If num_nonmet .eq. 3 .AND. 1 bond is to an oxygen with only one
                non-metal bond then atom_type is S.o

1.9.2                 If num_nonmet .eq. 4 .AND. 2 bonds are to an oxygen with only
                one non-metal bond then atom_type is S.o2

1.9.3                 If num_bond .ge. 2 .AND. all bonds are single then atom_type
                is S.3

1.9.4                 If element_symbol is S and none of the above then atom_type
                is S.2

另外,PhSO2NH2   PhNHSO2Me  处的N应该是N.pl3吗,    PhSO2NMe2呢
