使用的命令和输出的warning如下:
[root@localhost mol2]# antechamber -i niy.mol2 -fi mol2 -o niy.prepi -fo prepi -c bcc -at amber
Unknown bond type for BOND(C6-C7:Ar), assuming it is a single bond
Unknown bond type for BOND(C6-C8:Ar), assuming it is a single bond
Unknown bond type for BOND(C7-C9:Ar), assuming it is a single bond
Unknown bond type for BOND(C8-C10:Ar), assuming it is a single bond
Unknown bond type for BOND(C9-C11:Ar), assuming it is a single bond
Unknown bond type for BOND(C10-C11:Ar), assuming it is a single bond
Unknown bond type for BOND(N13-O14:Ar), assuming it is a single bondTotal number of electrons: 118; net charge: 0
请问为何程序无法识别出这些bond type?如何才能让程序识别?
另外得到的prepi文件为:

好像硝基的两个氧原子没有指定好:
21 O14 DU E 20 19 17 1.237 119.954 179.910 -0.216500
22 O15 DU E 20 19 17 1.360 120.009 -0.017 -0.216500
请问我可以手动修改吗?如何修改?GAFF原子类型中氧有以下几种:
o : Oxygen with one connected atom
oh : Oxygen in hydroxyl group
os : Ether and ester oxygen
ow : Oxygen in water
请问第一种合适吗?硝基中的氧应该是哪一种呢?
