[gmx-users] Topology for Sphingomyelin

[Ganesh Shahane]

Dear Gromacs users,

I wish to simulate a mixed lipid bilayer of which one of the lipids is
sphingomyelin (PSM, 18:1-sphingosine and 16:0-palmitic acid) using Charmm36
ff. Towards this, I constructed the bilayer using Charmm-GUI but then was
surprised to find that its topology is not present in residue topology
database of Charmm36 ff.

Does anyone has any idea about where can I get topology for PSM? Or would
it be wise to submit it to paramchem to get its topology?

Thank you in advance.
