配体含金属,run autodock 时报错
求助:对接的小分子里含配体,在网上搜索了好久,终于在本论坛里找到了“大工-阿里巴巴原创教程2-金属酶的对接”教程,解决了AUTODOCK添加默认原子类型的问题,rungrid修改参数文件.dat后也不再报错,金属原子得以识别,在此感谢大工-阿里巴巴及各位回帖的大侠们可悲剧的是,在最后运行Run AutoDock时报错
以下是我的gpf和dpf文件,请帮忙指正

我的小分子是氯化乙基汞,没有S,不知道为啥dpf文件里有这一行:ligand_types C Hg Cl SA # atoms types in ligand
所以在跑AutoDock时报错
我把ligand_types C Hg Cl SA 里SA删掉,又删掉map PAD.rigid.SA.map # atom-specific affinity map这一行,可还是报错
求助,求助!!
你的这个小分子(氯化乙基汞)不太适合用AD来做分子对接。阿里教程里面的是针对 蛋白含有金属原子! 可以尝试用arguslab这个软件来做含有非常见金属的对接 嗯,谢谢,虽然该问题我已经解决了,不过貌似对接效果确实不怎么好,我再用arguslab做一下
