[gmx-users] aliphatic hydrocarbon parameters

[T. Zaraiskaya]

hello all,

i am using LCH2 and LCH3 atom types introduced in ffG43a2x for lipid
aliphatic chains;
which function should i use for proper dihedrals in lipid chains?
func 1 and gd_17 from ffG43a2xbon.itp or
func 3 Ryckaert-Bellemans.?

2) ffG43a2x is it the same as 45A3 from  J.Comp.Chem. 22(11) 1205-1218 ?

thanks in advance,
