       使用Autodock计算格子时,run ---runautogirid之后就会出现附图这样的提示。虽然也能继续计算下去,但是想请问大家,为什么每次都出现这样的警告提示(图中红框处)呢?
      
       autogrid4: WARNING: I just prevented an attempt to take the arccosine of 1.000000, a value greater than 1.

同学,以后AD出现问题了~先把问题在google里搜一下
比如这个: http://mgl.scripps.edu/forum/viewtopic.php?f=9&t=1759
This message is printed from the section of autogrid which calculates bond-vectors for oxygen H-bond acceptors when 't0' is smaller than -1:

Here an explanation of t0:
/*
** t0 is the angle out of the lone pair plane, calculated
** as 90 deg - acos (vector to grid point DOT lone pair
** plane normal)
*/

As to specifically why it was printed in your case, I can only hypothesize that there may be non-standard bond lengths or disorder in the oxygen's neighboring atoms which were used to calculate the lone pair plane...
意思就是你的氧原子相邻的原子可能有问题,或者有不合理的键长~~

首先,非常感谢你的建议。我在的校园网最近打不开谷歌。以后能打开我会尽量尝试搜索的。
再次,虽然官网上面的这个相同问题的解答,只解释了原因却没有提出解决方法。但是我在官网上搜索我在autodock中遇到的另一个问题时,按照上面的解决方法,一并把我这两个问题都解决了。
所以非常感谢,非常感谢!:victory:

小朋友能告诉我们你是怎么解决的不?
