Here post your question
When I tried to run the follwing command to add the ions to neutralize the system
gmx grompp -f ions.mdp -c protein_solv.gro -p topol.top -o ions.tpr
I am always getting this error, I am sure all files are in the same directory
Topology include file “./amber14sb_OL15.ff/forcefield.itp” not found
do I need to write a special mdp file for my system ?
