hi all...
I am simulating a protein with Fe-S cluster. What is the protocol for generating a .rtp file with Fe-S topology...As i am using ffG43a1 forcefield.. i searched FFG43a1bon.itp file for Fe-S bond, angle and dihedral type... but it is not there..what i should do?.. If anyone have the idea of the procedure..please outline me the procedure..

Then the exceptionally difficult task of parameterization falls to you. Running a simulation with an Fe-S cluster will require very advanced knowledge of Gromacs and the force field for which you are designing the parameters. Take special note of the information here:
