gromacs配体力场电荷的问题
本帖最后由 kangsgo 于 2015-11-13 00:51 编辑我先教程在线服务器PRODRG 2.5的方法建立的力场电荷文件如下(感谢李继存老师和bioms群里的兄弟姐妹的指导):

群里和教程说这个做出来不准,用ATB较好,于是我用它做了一个,如下(感谢atom和飞天的指导):

但是它为何有两个的原子数都不相同·····所以我又用gaussian和ambertools做了一下(感谢宇后春来和李继存老师的指点)resp,电荷如下:

所以我有点迷茫了···我应该如何将其后面生成的电荷给转入进去呀?
你在个问题几年前已经被群里的大神完美解决了,http://blog.sina.cn/dpool/blog/s/blog_6ae686e701011of3.html 你好!我最近也在学习这个问题,想问一下,如果这个配体的电荷不准确,对后面的结果有什么样的影响? 本帖最后由 kangsgo 于 2015-11-12 12:41 编辑

不可以再使用gromacs的力场了么 wcyang 发表于 2015-11-12 09:25

小木虫上有人说影响非常大
