在我的粗粒化体系进行能量最小化后,表示出steepest descents did not convergr to Fmax <10 in 1001 steps。我也试过200步结果依然如此…重新做发现在蛋白真空min的时候就出现这个情况……
我试着往下继续做预平衡,mdp文件如下 (, 下载次数 Times of downloads: 26)

查了官网的errors,说是“ LINCS/SETTLE/SHAKE warningsSometimes, when running dynamics, mdrun may suddenly stop (perhaps after writing several pdb files) after a series of warnings about the constraint algorithms (e.g. LINCS, SETTLE or SHAKE) are written to the log file. These algorithms often used to constrain bond lengths and/or angles. When a system is blowing up (i.e. exploding due to diverging forces), the constraints are usually the first thing to fail. This doesn't necessarily mean you need to troubleshoot the constraint algorithm. Usually it is a sign of something more fundamentally wrong (physically unrealistic) with your system. See also the advice here about diagnosing unstable systems.”
