Check ions.itp and use the names required by your chosen force field.

        when i run the given command i.e,

        grompp -f minim.mdp -c 1AKI_solv_ions.gro -p topol.top -o em.tpr
        It is showing fatal error:No such molecule type NA.
        How could I troubleshoot this problem?


    Ion naming is listed in ions.itp - the "NA" name works for all force
    fields in the Gromacs 4.5.x series.  Older versions had force
    field-specific naming so you will have to change the name
    accordingly if you're using one of these versions.
