NAMD复合物分子动力学菜鸟求助~~!!

请教各位大侠!
小弟正在学习NAMD做复合物分子动力学,水球和水盒子结果如下,跪求大侠指导~!
水球结果如下:
TCL: Running for 2500 steps
ERROR: Constraint failure in RATTLE algorithm for atom 1202!
ERROR: Constraint failure; simulation has become unstable.
ERROR: Constraint failure in RATTLE algorithm for atom 480!
ERROR: Constraint failure; simulation has become unstable.
ERROR: Constraint failure in RATTLE algorithm for atom 763!
ERROR: Constraint failure; simulation has become unstable.
ERROR: Constraint failure in RATTLE algorithm for atom 471!
ERROR: Constraint failure; simulation has become unstable.
水盒子结果如下:MINIMIZER SLOWLY MOVING 20075 ATOMS WITH BAD CONTACTS DOWNHILL
听了几个大牛建议,把受体断的地方修补了loop,conf中加入了margin=3,但还是跑散了,不知各位大侠有何建议?
小弟发帖不多,银子有限,先谢过各位大侠了!!
