1 ; New format introduced in Gromacs 3.1.4.
2 ; Dont use this forcefield with earlier versions.
4 ; This residue database includes new reparameterized sidechain dihedrals
5 ; from Kaminski et al (JPCB, 2001) that override the default atomtype-based
6 ; dihedrals. We use set 2 for SER and THR, set 2 for ASP, and the better
7 ; separate dihedrals for LEU and VAL instead of the combined ones, since we
8 ; can specify them here without using introducing extra atom types.
9 ; (That was the reason they were combined in the paper).
11 ; NB: OPLS chargegroups are not strictly neutral, since we mainly
12 ; use them to optimize the neighborsearching. For accurate simulations
16 ; Column 1 : default bondtype
17 ; Column 2 : default angletype
18 ; Column 3 : default proper dihedraltype
19 ; Column 4 : default improper dihedraltype
20 ; Column 5 : This controls the generation of dihedrals from the bonding.
21 ; All possible dihedrals are generated automatically. A value of
22 ; 1 here means that all these are retained. A value of
23 ; 0 here requires generated dihedrals be removed if
24 ; * there are any dihedrals on the same central atoms
25 ; specified in the residue topology, or
26 ; * there are other identical generated dihedrals
27 ; sharing the same central atoms, or
28 ; * there are other generated dihedrals sharing the
29 ; same central bond that have fewer hydrogen atoms
30 ; Column 6 : number of neighbors to exclude from non-bonded interactions
31 ; Column 7 : 1 = generate 1,4 interactions between pairs of hydrogen atoms
32 ; 0 = do not generate such
33 ; Column 8 : 1 = remove proper dihedrals if found centered on the same
