Hi,

I mean that I can't possibly tell what your problem is, because you've
shared zero information. You probably want to look at the PDF reference
manual for the documentation of the "constraints" .mdp option. Whether that
matters depends what you've chosen, but I don't know that. See
http://www.gromacs.org/Support for clues on how you might succeed at
getting help from people.
