老师,我使用命令:
ztop.py -f "N;p=chit5_NH2.top;x=chit5_NH2.gro;site=B1:41-40,A1:59-60;resname=NH2_M;comment=NH2_med" --savelib
ztop.py -f "H;p=chit5_NH2.top;x=chit5_NH2.gro;site=B1:79-78;resname=NH2_H;comment=H as head" --savelib
ztop.py -f "T;p=chit5_NH2.top;x=chit5_NH2.gro;site=A1:21-22;resname=NH2_T;comment=T as tail" --savelib
将分子切出了头、中间体和尾3个部分,然后使用命令
ztop.py --loadlib -b HNT -o NH2.top,NH2.pdb
尝试连接3个片段,连接点的顺序显示也是正确的,最后得到的结构却完全散开了,您看看是什么原因,其中哪一步有问题呢?另外I will add charge -144.92743462 to every atom to make system reach target charge -10000.000000 这个操作是出于什么考虑呢?
