采用Discover优化结构找不到相应参数
我采用Discover模块优化糖分子时总是出现以下内容,compass,pcff,cvff力场都试过了,还是出现以下提示:Error: Energy expression: cannot find parameters for bond: H1(ag_m)-C1(ag_m)

想问下有没有哪位大侠遇到过这种情况?最终怎么解决的啊?现在卡到这里了,很是郁闷啊,急需帮助!
你是在什么条件下优化的?单纯的糖分子?发图 谢谢,刚看到回复,图片我发上去了,是糖胺聚糖的一个结构单元,优化结构总是失败! 谢谢,结构我发上来了,麻烦帮我看下
元素的名称与力场文件中的无法对应,好像是 :L:L:L:L:L
