hi i am working of protein ligand binding free energy calculation, i have seen some tutorials, like from alchemistry websites and from some paper works. i made ligand topology with acpype (amber.ff) and used pdb2gmx for protein topology, then i combined gro files to make a complex. now i dont know how to make complex topology. i already studies and used tutorials from Bevanlab but it doesnt provide info about how to include protein and ligand as one moleculetype. and also how should i get the dihedral, angle and distance restraints. i studied gromacs manual about this but it doesnt provide any direction. if anyone have some tutorial, kindly suggest. Thanks in advance
