Ahh... I mean the system you are simulating, namely the combination of the coordinate file (.inpcrd or .rst7 in AMBER) and the parameter file (.prmtop or .parm7).

The reason for this phenomenon is the number are to large to print. This normally indicate the configuration of your system is too bad. Check if there are any bad contacts such as overlapping atoms, wrong definition of chemical bonds...

Another suggestion I can provide is to finish the AMBER tutorial at http://ambermd.org/tutorials/, at least the introductory ones.

Thanks for the answer!

But just to clear any doubts, when you say"system", do you mean the "chemical system" or the "system" related to Hardware and Software configuration?

Thanks in advance!

Ok! Thanks for clarifying !

Dear Zhaoxi Sun , we have checked if there were any bad contacts such as overlapping atoms, wrong definition of chemical bonds, as example as you've said but it passed all the tests.

Could you suggest where else could we look? Or what else could be the problem?
