Thanks Justin,

My goal is to keep certain part fixed and move only a few of the residues (case is like providing flexibility to the site of interest only).
SO , do I need to specify the residue using some index file ?
or is there some other way to specify the part of molecule for position restraining ??


Make an index file with the residues you want to keep fixed, and pass it
to genpr to generate a new posre.itp that corresponds to those residues.

        Hi there,
         I want to run MD over a part of my molecule , for few residues
        only (not the whole molecule).
        Can I do it using GROMACS ?
        I searched for the online documentation and mailing list, but
        unable to get appropriate information.
        If somebody has already tried such things earlier, please
        suggest and direct me for appropriate link and address.


    Well, if your goal is to keep certain parts fixed and allow others
    to move, probably the easiest way to do it is to apply position
    restraints to the "fixed" part.
