[gmx-users] State B IN Topology

[Sana Saeed]

HIi am making topology of protein ligand complex for calculating binding free energy. my question is do i need to define state B manually or is there any automatic method to do that. Second question is i want of number my ligand atom numbers from the number where protein atom numbers are stopped , like if protein's last atom is 100 then i want to start my ligand from 101. manually it will take lots of time because i will have to modify all the sections in topology file, is there any easy method? or i need to do that manually.
