Query on a recurring error during md simulation

GROMACS version 2024.2:
GROMACS modification: Yes/No
Here post your question - During my working on md simulation using gromacs for my summer project, i am continuously getting stuck at the adding ion step of gromacs protein-ligand complex tutorial, the error is about the topology coordinates not matching the sol.gro coordinates, but i am following the steps to the utmost precision without any fault and even then this specific error is occuring.


this following error is occuring, please help me in solving this error, your help will be much appreciated.

My guess is you forgot to remove the water molecules from the topology file that you replaced by ions.

But I haven’t had the chance to add ions, I had created the topology file of receptor-ligand complex using the gro file and then solvate the gro file.
