Hi,
Thank you for your response. It is a protein molecule containing 610 amino acid residues.

you didn't answer my question.
please inspect the molecular structure at the time point where the error occurs.

Thanks and regards,
Nishtha

        Hello everyone,
                            While trying to do the RMSD analysis of my
        trajectory file I am facing the error " Too many iterations in
        routine JACOBI". I have gone through the archives which suggests
        that such problem arises if there is mismatch between the
        reference structure and trajectory. However in my case the
        problem lies somewhere else because, using the same .tpr file
        and .trr file I have done RMSD analysis earlier also and it
        worked fine.  The g_rms program is giving error but, for the
        same set of input files g_rmsdist is working fine.

    g_rmsdist doesn't use lsq fitting.

    Is you molecule linear or planar? (i.e. not 3D)?

               Kindly help.
        Regards,
        Nishtha
