尝试用动力学研究一分子,用GaussView建模后获得pdb文件(已简化为能重复出相同报错的简单分子,如下图所示)
运行:
- antechamber -i Untitled-1.pdb -fi pdb -o Untitled-1.prepin -fo prepi -c bcc -s 2
复制代码 后,给出如下信息:
- Running: /home/amberuser/Program/amber16/bin/bondtype -j full -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac
- For atom[3]:B, the best APS is not zero, bonds involved by this atom are frozen
- For atom[4]:AL, the best APS is not zero, bonds involved by this atom are frozen
- The frozen atom type can only be 1, 2, 3, 7 (aromatic single), 8 (aromatic double)Error: cannot run "/home/amberuser/Program/amber16/bin/bondtype -j full -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac" in judgebondtype() of antechamber.c properly, exit
复制代码 似乎是bondtype子程序未能识别出正确的成键类型,经检索未能找到有效地解决方法。想问如何帮助antechamber识别这一分子?或如何手动指定每个键的类型?
任务使用的 pdb 文件、运行 antechamber 生成的 ANTECHAMBER_BOND_TYPE.AC0 文件和 ATOMTYPE.INF 文件见附件
