| 请教一下,opc水的问题。一个纯水的盒子,需要选择一个水分子作为溶质solute set,用free energy perturbation计算溶剂化自由能, 报错如下。。。 Non-default thread affinity set probably by the OpenMP library, disabling internal thread affinity ------------------------------------------------------- Program: gmx mdrun, version 2020.6-MODIFIED Source file: src\gromacs\mdlib\settle.cpp (line 194) Fatal error: The [molecules] section of your topology specifies more than one block of a [moleculetype] with a [settles] block. Only one such is allowed. If you are trying to partition your solvent into different *groups* (e.g. for freezing, T-coupling, etc.), you are using the wrong approach. Index files specify groups. Otherwise, you may wish to change the least-used block of molecules with SETTLE constraints into 3 normal constraints. For more information and tips for troubleshooting, please check the GROMACS website at http://www.gromacs.org/Documentation/Errors 求溶剂化自由能,settle报错,请问有人会opc水的这个怎么改吗 还有其它水模型模型,比如TIP4P,TIP5P,极性水分子模型,这个settle问题有没有模板。 |

别自己在标题里手写[GROMACS]这种标签,这次给你改了,以后注意
提示写明了,只能有一个moleculetype出 ...

多谢版主。。。这个settle删掉以后对计算结果的影响有吗?不知是否研究过?特别是溶剂化性质

你用柔性水就不需要写,根据预处理语句可知此时不生效
主流的水模型大多都是基于刚性模型做的参数化, ...
