[gmx-users] atomtype OW is not found

[Doaa Ragab]

 I am running membrane simulation in gromacs using the posted tutorial: http://www.bevanlab.biochem.vt.edu/Pages/Personal/justin/gmx-tutorials/membrane_protein/03_solvate.html

at the step of 
grompp -f minim.mdp -c dppc128.gro -p topol_dppc.top -o em.tpr
I am usually getting the error that: atomtype OW is not found.
Can you help me in this.
Thank you
Doaa
