Hi GROMACS users,
sorry please disregard the earlier message realised it was too long.
i am new to GROMACS. i have been trying to run the Villin Benchmarks using
the conf.gro, grompp.mdp and topol.top file provided with the benchmark
folder. i giving the grompp command as follows

grompp -f grompp.mdp -c conf.pdb -p topol.top -o em.tpr

and after that i get this message,

Fatal error:
number of coordinates in coordinate file (conf.pdb , 9389)
             does not match topology (topol.top, 0)

After going through the GROMACS mailing list I realised this is a classical
mistake which everyone makes. that's fine, but even after making the changes
as pointed out by many users that check the number of atoms in topol.top and
conf.gro file i am still getting the same error.
i am providing in the email conf.gro and the topol.top file. can anyone of
you plz suggest as to what is wrong. where i have to make the changes
inorder for me to run the simulation.thanks.
the file are provided below.
