GROMACS modification: Yes/No
Here post your question Hello
Im trying the MD Simulation of a Protein-RNA complex using the Amber force field. I request some suggestions for creating the topology file for the Nucleic acid molecule.

Looking forward for kind reply

I would suggest using CHARMM-GUI as a starting point.
If you are among experienced user, using tleap or xleap in AMBERTool actually recommended.
