This issue is commonly reported. Making haphazard changes to your topology is a
bad idea. Please search the list archive (available through the interface at
the Gromacs site), and consult the following:

Dear All,
when I want to use grompp program
grompp -f minim.mdp -c solboxbrady.gro -p bradymod.top -o minimbrady.tpr
I got the following error message
Fatal error:
[ file "spc.itp", line 41 ]:
Atom index (1) in settles out of bounds (1-0)
So I tried to modify the topology file by removing the following
; Include water topology
#include "spc.itp"
#ifdef POSRES_WATER
; Position restraint for each water oxygen
[ position_restraints ]
; i funct fcx fcy fcz
1 1 1000 1000 1000
#endif
; Include generic topology for ions
#include "ions.itp"
Since there is no needs also ions.itp , because I didnot add any ions to the
structure. Is this right?
Finally, I tried to use grompp again with the modified topology file. I gety a different error message
Fatal error:
No such moleculetype SOL
I donot know why SOL (water) didnot recognized by grompp !!!!!!
How can I fix these problems ?????????????????
