[gmx-users] GROMOS force field for sphingomyelin and cholesterol

[凌未风]

Hello everyone:

I am planning to do some simulation of bilayer mixtures (maybe also include protein). I am planning to include sphingomyelin and cholesterol in my system. Could anyone let me know where to get the gromos force filed for these two molecules (I am using gromos force field for some reasons)?

Thanks very much. 

Cheers,
