Dear Amber users!
 
I have a problem with MD. I am doing dynamics on ligand-protein
complex in water. During my MD (527ps) a got a message:
 
Coordinate resetting (SHAKE) cannot be accomplished,
     deviation is too large
     NITER, NIT, LL, I and J are : 0 1 2089 4153 4154
 
     Note: This is usually a symptom of some deeper
     problem with the energetics of the system
 
Are I and J atoms number?
I have tried to increase box, but the problem remains.
I looked at the structure using VMD. If 4153 and 4154 are
problematic atoms numer than this is a ligand problem, but it
seems perfectly ok.
 
Please help me.
