[gmx-users] lipid parmaters

[Revthi Sanker]

Dear all,
I am trying to perform all-atom simulations of a protein+lipid system with charmm27 forcefield in gromacs . Can anyone suggest me from where I could obtain the paramaters( *.itp file)  from? I tried searching the lipid-book but in vain.cGENFF and swissparam are exclusively for small molecules and not for biomolecules. I need parameters for cholesteryl oleate and dioleyl phosphotidyl choline. 
Kindly provide your valuable suggestions.
Thank you all in advance.

Regards,
Revathi
