hi gromacs users
i got error in step four in protein-ligand complex how can i fix it:
Fatal error:
number of coordinates in coordinate file (solv.gro, 36526)
does not match topology (topol.top, 365267)
when i want to ran this:
grompp -f em.mdp -c solv.gro -p topol.top -o ions.tpr
i add my ligand drg.gro in protein_processed.gro.
Thanks,,
Regards,,

hi gromacs users
i got error in step four in protein-ligand complex how can i fix it:
Fatal error:
number of coordinates in coordinate file (solv.gro, 144131)
does not match topology (topol.top, 144171)
when i want to ran this:
grompp -f em.mdp -c solv.gro -p topol.top -o ions.tpr
i add my ligand drg.gro in protein_processed.gro.
beside i cant find conf.gro that you say in this toturial:

conf.gro is the default output name from pdb2gmx; it's just a typo in the tutorial.
The solution to your problem is always the same - proper bookkeeping. Your
topology specifies something that is not in the coordinate file (the ligand,
perhaps?) that has 40 atoms.

Actually, it's not a typo:
Copy 3HTB_processed.gro to a new file to be manipulated, for instance, call it
"conf.gro."
It's just a safety measure in case you mess something up; you haven't wrecked
the actual pdb2gmx output. Perhaps I should call it something different to
avoid clashes with default names. Apparently I had even confused myself before
I checked...

Dear Yaser,
Gro file is sensitive and you should update the number manually after
adding the ligand atoms to the protein.gro file. Check the first line of
your protein.gro and ligand.gro. In the complex.gro the first line should
be the summation of both. Gromacs does not perform it manually. Kindly chck
again and rerun the grompp.
Good luck

Incorrect formatting or contents of the .gro file should not trigger this fatal
error; there are other error messages if there are too many or too few atoms in
the .gro file.

Dear Justin,
Thanks for reply
I am using following attached mdp file
In raw trajectory protein molecule appears to be broken but ions around it
. So I processed the trajectory with trjconv whole option followed by
nojump.
After that the protein appear on one side and ions on other
Thanks
Vinod
