Hi After:
pdb2gmx -f mymol.pdb -water tip3p editconf -f conf.gro -bt dodecahedron -d 1.3 -o box.gro genbox -cp box.gro -cs spc216.gro -p topol.top -o solvated.gro I typed: grompp -f em.mdp -p topol.top -c solvated.gro -o em.tpr where em.mdp is my energy minimization file and I got: Fatal error: Unknown bond_atomtype C2 What is here the problem? All atom types should be declared by me, I guess.
