[gmx-users] tabulated potentials for dihedrals - regd

[ramesh cheerla]

Dear Gromacs users,

                          I am using tabulated potentials for the dihedrals
of  my system, the dihedral function I am using is Summn over 'n'  0.5*K [
( Cos  n(phi-phi0)] , Here 1<= n <= 3 .
The C-O-C-C dihedral of my system has three folds those are  n= 1 , 2, 3
and three different K ( force constant ) values one for each "n" value.
Here my doubt is while specifying the "k" value in the "ffbonded.itp" ,
Which K value do I have to take ? or can i take sum of all these "k"
values  and mention that value in ffbonded.itp ?

Please help me in this regard,

Thank you in advance,

Regards,
Ramesh cheerla.
