[gmx-users] Multiple torsional parameters

[Pedro Alexandre Lapido Loureiro]

Hi,

I am implementing the lipid force field of Smondyrev & Berkowitz (J Comp Chem 
20, 531 - 1999).
The problem is they use two expressions for one dihedral, such as:
LC2  LC2O    1  0.0   5.8576   3
LC2  LC2O    1 180.0  4.184    1
I have built my .top file in this way.
When I run grompp, there is a warning saying the former parameters will be 
overridden and the latter will be used.
How can I solve this?
(Sorry if a matter like this has been already discussed in the list...)

Cheers,
Pedro.
