Hello,

I believe adding iwrap=1 will fix your problem. This will wrap any
particle leaving the original box back into that box, which should
prevent diffusional processes from moving a particle beyond to a
position too large to be included in the restart file (thus resulting
in *******s).

Good luck!
Jason

> Thank you for your immediately reply. Would you think that adding "iwrap=1 " in our simulation could solve my problem? According to your suggestion, I have resimulated the complex. We have simultaneously simulated the protein in another PC workstation, when I performed this simulation. But the error occur at 40ns, would you think that just repeat the simulation process with the same input file could solve this problem?
