I thing the the function is not written well... It is: Vd=k_phi(1+cos(n*phi-phi_eq)) Antonia >prasun kumar said: > --000e0cd20d869ab935046434ec49 > Content-Type: text/plain; charset=ISO-8859-1 > Content-Transfer-Encoding: 7bit > > Respected all > I drew the structure using the drawing tool

Hi, the function used by GROMACS is Vd (öijkl ) = kö (1 + cos(nö − ös )), for proper dihedrals (periodic type). Take a look at Chapter 4, of GROMACS-4-0 manual. Antonia >prasun kumar said: > --000e0cd20d869ab935046434ec49 > Content-Type: text/plain; charset=ISO-8859-1 > Content-Transfer-Enc

Dear Prasun, I think you can get the help of Chem 3D for fixing this problem. First you have to generate the topology with Chem 3D then get the gromacs format with PRODRG server of the same. I hope it will help you, with regards anil On Mon, Mar 2, 2009 at 2:21 PM, prasun kumar wrote: > respe
