Hi Justin,
Thanks again... . Actully I have a question: I have 1836 atoms (572 water
and 1 molecule with 120 atoms). In top of my file.gro I have 1836 and in
topology in [molecules] I have c60ch3 1; and SOL 572 which means the same as
above. So how I should change it to get rid of error...??/ Thank you in
advance.../Jamie

Make sure you have only one [ molecules ] section. I think Justin's probably picked your problem, inasmuch as you've just renamed a molecule.top to molecule.itp without removing the directives that should not be in an .itp file.

Hi Justin,
Oh yes. I had a line that include ff again and I deleted that (is that
ok)? now I got a new error related to "number of coordinates in

That's more than OK, that's correct.  As Mark pointed out, there should
only ever be one invocation of [ defaults ] in a topology.

coordinate file does not match topology..." I should fix this one now!!
Simple one to fix.  Figure out where the duplicate or missing molecules are
within the topology.  I'm guessing your molecule.itp was really a
molecule.top, complete with [ defaults ], [ system ], and [ molecules ]
directive, right? None of these should be present in an .itp file, only a
.top.

Thanks a lot/Jamie

   Can you post the contents of molecule.itp?  The first #include for
   the force field is likely not the problem; you've probably #included
   it again in molecule.itp.

              Jamie,

              The idea is the same. Some directive is not at its place. I
              cannot say
              which is exactly because I don't see all the picture with
       your
              topology file (+included files). Write the sequence of
       directives as
              they go in .top (+included .itp) and then we will see
       what sections
              must be shifted or maybe just swapped.
