Dear justin Hi, In my simulation with ff53a5 when I do this command pdb2gmx -f name.pdb -ter -ignh -water spce .I find this error .C-terminus: None Now there are 14 residues with 138 atoms Making bonds... Opening library file /usr/local/gromacs/share/gromacs/top/aminoacids.dat Number of bonds was 142, now 139 Generating angles, dihedrals and pairs... Before cleaning: 210 pairs
