Respected Sir,
               I am new user of gromacs. When I use the following command
gmx grompp -f ions.mdp -c 1aki_solv.gro -p topol.top -o ions.tpr

I get the following error :Number of coordinates in coordinate file does not 
match topology file.
Please tell me how can I correct the number of coordinates in gromacs?

Since you've (presumably) already solvated the system, you probably forgot to let genbox adjust your topology for you via the -p option. Based on your file naming, I assume you're following my lysozyme tutorial, which lays everything out exactly, so be sure you're using the exact commands and you know what each option is doing.
