Your ffcharmm.itp file lacks a necessary line at the very top:<br>
<br>
#define _FF_CHARMM<br>
<br>
Without this line, grompp does not know which force field you are using, and hence everything breaks down when other .itp files are called.<br>

Hi All,<br>
I have downloaded pdb file and required .top and .itp file<br>
from the site <a href="http://www.bioinf.uni-sb.de/RB/" target="_blank">http://www.bioinf.uni-sb.de/RB/</a> for DOPC<br>
simulation. Now when I execute the command<br>
grompp_d -f em.mdp -c charmm-s22-100ns.pdb -p topol.top -o<br>
dopc.tpr -e ener.edr -t traj.trr I got the error " Fatal error:<br>
[ file tip3p.itp, line 42 ]:<br>
Atom index (1) in settles out of bounds (1-0).<br>
This probably means that you have inserted topology section<br>
"settles"<br>
in a part belonging to a different molecule than you intended to.<br>
In that case move the "settles" section to the right molecule.<br>
-------------------------------------------------------<br>
<br>
Attached is the em.mdp file I am using. Please help me how to<br>
solve this problem.<br>
<br>
<br>
Please see here:<br>

<br>
The .mdp file is not the source of the problem; the topology is. If<br>
you need more help, you'll have to post the relevant section.<br>
